Synaptics Clickpad touchpad buttons are not working

Hi Serkan,

Please be sure to confirm this issue exists with the latest development release of Ubuntu. ISO CD images are available from http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains, please run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 582809

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

Hi Serkan

Thanks for posting this. Does this patch enable two-finger clicking &
scrolling?

No, that is the feature i am missing the most. This only fixes the detection of the touchpad as a clickpad for the buttons. It does this by using at the product id.

Other synaptics goodies as two finger tap right click and three finger tap middle click are missing too. Also click and drag is really hard, if not done correctly the mouse cursor jumps around all over the screen and scrolls the active window wildly.

Unfortunately, this very same patch that fixes the ClickPad breaks my 3-button touchpad -- see bug 612591 .

I'd like to reopen the bug, but being a n00b i probably am not allowed to.

Anyhow, I'm having the same problem with a HP Pavilion dv7 3051sg. It's from the same generation as the HP Envy15, so it is likely to be the same touchpad - at least dmesg says the same thing as above.

The patch works in so far that I can actually left/right click on the lower parts of the clickpad that have been labeled as the trackpad buttons - but a click is not registered while there's still a finger on the touchpad! I have to lift the finger from the touchpad, then click on the button areas below, then place the finger on the touchpad again in order to e.g. drag & drop.

Also, as soon as two fingers (such as when dragging and clicking at the same time) are on the clickpad, the cursor quite often jerks to the left suddenly.

I assume this has got to do with the master/slave click-approach on multitouch touchpads...

Tried getting SHMConfig to work by enabling it in xorg.conf, but synclient -m 50 still tells me that it cannot access the shared memory area...

You might want to give a try to this patch for xorg synaptics driver:

https://patchwork.kernel.org/patch/93837/

I have the buttons working but you can forget about click+drag events, the cursor jumps all over the screen, can't move windows and can't select text with the touchpad.

Serkan: from what i gather, this patch is already included in ubuntu 10.04 - otherwise the buttons would not work at all, right? ;-)

Click and drag works, as long as you lift your finger from the clickpad and *only* click on the button area. text selection works the same way...

Serkan: that inability to click & drag is probably due to the mouseclick-event not registering a secondary click as an event, with the finger on the trackpad itself being the primary click (touch the touchpad -> click left mousebutton area -> drag). If the drag-event is from a secondary click and the mousebutton is the primary click (don't touch anything -> click left mousebutton area -> drag) it works though. Seeing how primary and secondary clicks already work somewhat, it should be possible to fix that behaviour without going to multitouch-APIs like MPX or Xi2....

also, a middle mouse button would rock! ;-)
Looking at your patch that should be fairly easy to implement, and since you cannot use left+right click to simulate it on that clickpad it would really be useful, seeing how many Linux-users use the middle klick, e.g. in the shell...

I just updated to xf86-input-synaptics in the latest dev version 1.2.99.1 (before: 1.2.2-1ubuntu4) to no avail. No change, it still works as buggy as described above...

Are you sure that patch is already applied? Just did apt-get source xserver-xorg-input-synaptics and grep the source for clickpad and can't find anything.

Now we are on Maverick beta and Clickpad *still* does not work.
Someone got it working in OpenSUSE by using a custom repo (as in http://www.andreas-demmer.de/en/2010/07/18/testbericht-linux-auf-dem-hp-envy-14/ ).
It is a little upsetting since many new laptops are shipping with this kind of touchpad.
Is there *anything* we can do to help fixing it? Is there any patch to make it work in 10.10's kernel?

The Clickpad button detection was performed in the kernel in Ubuntu 10.04. The upstream kernel has since been changed so that the Clickpad button detection is now performed in xorg-input-synaptics. The problem is that the current Ubuntu 10.10 kernel uses the upstream kernel with patches from 10.04 for button detection. That means that there is conflicting code in the Ubuntu 10.10 kernel. Furthermore, I don't think there are provisions in Ubuntu 10.10's xorg-input-synaptics for Clickpad button detection.

The attached patch will clean up the current Ubuntu 10.10 kernel so that button detection is performed in the kernel like Ubuntu 10.04. However, The best solution would be to use the upstream Clickpad code in the kernel as well as in xorg-input-synaptics. Additionally, there are patches available to make the LED on the Clickpad work properly that should be applied.

Is there any way we can get this one fixed before Maverick is released?
A lot of people are not going to like the regression. The Clickpad's buttons worked fine in Lucid.

https://build.opensuse.org/project/show?project=home:tiwai:clickpad
It is for 2.6.32, methinks. But maybe...

tob, I applied your synaptics.diff to kernel 2.6.35-22-generic and it fixes the corner clicks but it also breaks horizontal scrolling. Does horizontal edge scrolling work for you?

Just for clarification for kernel newbies like me, to apply this patch, I do something like:

$ sudo apt-get build-dep --no-install-recommends linux-image-2.6.35-22-generic .config
$ apt-get source linux-image-2.6.35-22-generic
$ cd linux-2.6.35
$ pushd drivers/input/mouse
$ patch < ~/Download/synaptics.diff
$ cp /boot/config-2.6.35-22-generic .config
$ popd
$ make modules

Is there a way to just build the needed module? Which module do I need to build and install?

Bill

@pauls
I left the button detection that was used in Lucid untouched in the patch. Basically, it disables the bottom button area of the touchpad to use for buttons. This was done so that the mouse cursor doesn't bounce around the screen when you press a button. Unfortunately, this is the same region that is used for horizontal scrolling. I attached a quick and dirty patch that will only disable the button region of the touchpad when the your finger pressure is greater than 77. However, this number will probably not work for everybody because the z value is different for different people. You can use "synclient -m 100" to find a value that will work for you. I think that there are much better ways of doing this, but it should be done in xorg-input-synaptics.

@WaywardGeek
I found this script somewhere a while ago. It is quite useful for compiling the psmouse module.

Thanks for the compiler tip, I thought we had to recompile the entire kernel and was taking 6 hours on this little atom.

Trying your latest synaptics.diff with z=77 fixes horizontal scrolling, but I can't get a high enough z to get the left / right clicks to work.

When I run synclient -m 100, I get z values of around 45 when I click the lower left or right, and about the same z of 45 when I horizontal scroll. I'll try your patch with different z values and report back if I find a good compromize.

If the only reason you disable horizontal scrolling is for the jumpy mouse problem, there may be another way to deal with that, and it seemed to work on lucid for me:

synclient JumpyCursorThreshold=50

I put his in a startup program to run at startup.

If we can figure out how to identify this touchpad "MatchTag" we could include a quirk in the quirks file /usr/share/X11/xorg.conf.d/51-synaptics-quirks.conf to set it. A related post regarding quirks is at http://www.pubbs.net/201001/xorg/1033-xorgconfd-inputclass-feature-request.html

I need to fully read that post, but it looks like my lenovo s10 has this identifier:

 :~$ cat /sys/class/dmi/id/product_name
20040M18

Could you give me a synaptics.diff that enables both horizontal scrolling and left / right clicks, like lucid had? Then, I'll play around with the JumpyCursorThreshhold quirk idea and see if we can fix both problems.

@pauls
You should be able to apply both patches one at a time to the original in order to have the buttons and horizontal scrolling.

lol, I misunderstood and just applied the 2nd diff when I couldn't it to work. After applying both patches, with z=77 as you recommend, it works. But, I need

:~$ synclient JumpyCursorThreshold=50

to be able to select text.

I tried adding this to /usr/share/X11/xorg.conf.d/51-synaptics-quirks.conf

Section "InputClass"
        Identifier "Lenovo s10-3t quirk"
        MatchTag "20040M18"
        MatchDevicePath "/dev/input/event*"
        Driver "synaptics"
        Option "JumpyCursorThreshold" "50"
EndSection

but, it did not work on boot. Any ideas how to fix this?

@pauls
Try and use the "catchall" section in /usr/share/X11/xorg.conf.d/50-synaptics.conf

Section "InputClass"
 Identifier "touchpad catchall"
 MatchIsTouchpad "on"
 MatchDevicePath "/dev/input/event*"
 Driver "synaptics"
 Option "SHMConfig" "on"
 Option "JumpyCursorThreshold" "50"
EndSection

Yes that works, thanks for the tip.

Now if we could just get some priority on getting these changes implemented..

Tried the latest RC release of Kubuntu 10.10 and the problem as still not been fixed. It does not seem this bug is being giving priority by Ubuntu developers and might not be fixed in the 10.10 release circle. :(

Thanks Tob, your patch fixed the touchpad buttons for me.

my main concern with apply this patch or even upgrading to lucid is on whether this bug would be fixed in the ubuntu kernel before or during the 10.10 life cycle. and if it would be fixed would this patch be used in fixing it? I don't mind applying this patch what i don't want to do is applying the patch everytime there is a kernel upgrade (which happpens quite a lot on ubuntu).

Same for my HP ENVY 14 Notebook PC

I fix the right button issue with the next command:

 echo options psmouse proto=exps > /etc/modprobe.d/psmouse.modprobe

and then reboot

The fix eSe mentions may work for some people, but it doesn't work here. Using an HP dv7-4060us.

@tob

thanks,

no more jumping cursor, on:
- HP Pavilion dv7-4011eg
- Kubuntu 10.10 beta
- kernel 2.6.35-19-generic

changing

Section "InputClass"
 Identifier "touchpad catchall"
 MatchIsTouchpad "on"
 MatchDevicePath "/dev/input/event*"
 Driver "synaptics"
 Option "SHMConfig" "on"
 Option "JumpyCursorThreshold" "150"
EndSection

in /usr/share/X11/xorg.conf.d/50-synaptics.conf

I found the patch here: http://ubuntuforums.org/archive/index.php/t-75713.html

If i use this command i can click with right button and i can drag and drop but other problems are caused like I cant vertical scroll which before works fine.

Hi all,

firs of all I want to thank everybody for posting the useful comments

Anyway I applied the command of eSe (thanks for posting) which get my right button back to working. But as post the vertical and horizontal scrolling is not working. Another bad side-effect is, that the touchpad isn't longer recognized as touchpad by the mouse settings in ubuntu. So I installed gsynaptics where you can simulate a mouse-wheel by pressing a button. This works fine but is far from comfortable. So I changed everything back to normal

Changing the settings in xorg.conf.d as post by tob (thank you) helped my to get rid of the jumping stuff, but still I can't use the right button, as I don't know how to apply the patch posted by tob.

So my question, is it possible to post a step-by-step manual how to apply this patch or post a link here how to do it. I'm sorry, but I'm really haven't any idea what to do. Even the script (CompilePsmouse.sh) posted by tob the other day didn't help my at all.

Thank you all very much!!!

Cheers,

Jan

Same problem here on a HP tm2 laptop with synaptics clickpad touchpad....
THe reported patches seems to be not working here

It's possible to use dkms to build the psmouse module for the buttonless synaptics touchpad on some newer netbooks.

First make sure dkms package is installed.

Next download this patched source archive for the psmouse module from kernel 2.6.35-22-generic on maverick. I just posted it to this bug, it's called: psmouse-2.6.35-22-generic-patched.tar.bz2

In a terminal, unpack the source archive in /usr/src

Next, in a terminal, enter these commands:

sudo dkms add -m psmouse -v 2.6.35-22-generic
sudo dkms build -m psmouse -v 2.6.35-22-generic
sudo dkms install -m psmouse -v 2.6.35-22-generic

This should install the psmouse.ko module in /lib/modules/<kernel version>/updates/dkms. Reboot to load it.

If the mouse doesn't function properly, use this command to check if it's installed.

sudo dkms status -m psmouse -v 2.6.35-22-generic

If it's not, then try rebuilding it with

sudo dkms build -m psmouse -v 2.6.35-22-generic
sudo dkms install -m psmouse -v 2.6.35-22-generic

Once a new kernel is issued with a fix, then you can remove it with:

sudo dkms uninstall -m psmouse -v 2.6.35-22-generic
sudo dkms remove -m psmouse -v 2.6.35-22-generic --all

I also believe that dkms will automatically build and install it on any kernel upgrade, but haven't tested that yet.

After installing any kernel update, you can test with

sudo dkms status -m psmouse -v 2.6.35-22-generic

and if it's not built, use the above commands to build and install it.

Reboot to make it effective.

For more info, see man dkms for the official documents.

I would want to second Jan Bachmann here. It would be nice if someone with the know how can document how this patch can be applied. The release of Marverick is in a fews days and it might not be visible to see an official fix to this issue before release date due to fear of causing regression. Most new users would install Marverick and be pissed that they are unable to use their "touchpad" It would be nice to have a wikipage or some documentation or even a PPA with the necessary patch which we can point users to as a work around the problem. And would also be nice if this bug is added to the known issues release note and a pointer to the walkaround.

bigbrovar, I think I just did

Great pauls, all works fine now.

Note: remember delete /etc/modprobe.d/psmouse.modprobe if you created this

rm /etc/modprobe.d/psmouse.modprobe

Hi,

pauls thanks a lot for the detailed description!!!

So far it looks like I can work without my usb-mouse, finally ;)

I will inform myself about dkms...to see what I just did.

One more question: How can I find out that this issue is fixed in a new kernel?

Thank you very much again!

Cheers,

Jan

Jan, you should see an email if you're subscribed to this bug that a fix has been applied. Then, you can check the /usr/share/doc/linux-image-2.6.35-??-generic/changelog.Debian.gz for info on what bugs were fixes to make sure it made it into that update.

hth,

Thanks for the write-up pauls!

@Davide
Please post your dmesg if you are still having problems after applying my patch:
dmesg | grep -i synaptics

What is the difference between @tob's synaptics.diff patch and @Paul's patched psmouse source archive. would we have to use both patchs at the same time? or is it one or the other?.

Also if I apply @paul's psmouse patch would I be able to do vertical and horizontal scrolling. And what are the disadvantages of using this patch against the synaptic.diff file?

I am sorry if my question sound noobish. I just need to some understanding/clearifications

 It seems that for 7.4 model (Synaptics Touchpad, model: 1, fw: 7.4, id: 0x1e0b1, caps: 0xd04771/0xe40000/0x5a0400)
multifinger don't works because caps are d04771 and so, not ending in 3 (as if model were f. ex. d04773), that is what the driver looks for.
I've tested changing in synaptics.h
- #define SYN_CAP_MULTIFINGER(c) ((c) & (1 << 1))
- #define SYN_CAP_MULTIFINGER(c) ((c) & (1 << 0))
0 never should be used as it's for palm_detect bit that I know is set to 1, but it was only a test

With this change, multifingers works more or less. Touchpad detect the fingers and you can right click with two fingers or scroll, but you have to keep the fingers separated. The bad words, are that it conflicts with using the touchpad bottom area as buttons (now detected as two fingers), so it's no so useful...

Is there any specifications available for this 7.4 touchpad?

Thanks

I had the same problem with my touchpad on HP DV7-4050ez but Pauls patch works for me

@Anton
I have the exact same touchpad as you. I don't think this is related to the 7.4 firmware. I do not recommend the changes to synaptics.h that you posted. The newer Synaptic touchpads can either utilize a new multitouch protocol or the old absolute protocol. The Linux kernel does not currently support the new multitouch protocol so it uses the old absolute protocol. The touchpad doesn't report its multitouch capabilities when it is in the old absolute mode. However, 2 finger emulation still works by using the touchpad's width property to determine how many fingers are on the touchpad. You may need to play with some of the options in /usr/share/X11/xorg.conf.d/50-synaptics.conf if 2 finger detection doesn't currently work for you. Try playing with these options:
 Option "TapButton2" "3"
 Option "EmulateTwoFingerMinW" "5"
 Option "EmulateTwoFingerMinZ" "90"
 Option "VertTwoFingerScroll" "1"
 Option "HorizTwoFingerScroll" "1"
 Option "VertScrollDelta" "100"
 Option "HorizScrollDelta" "100"

Sorry for the off topic post. Multitouch problems should probably be handled elsewhere.

bigbrovar, the psmouse tarball that I attached is the linux 2.6.35-22-generic source directory for the mouse (linux-2.6.35/drivers/input/mouse), with both of the synaptics.diff patches applied already. If you take a look at the synaptics.diff files, you can see they apply to the synaptics.c source file in that directory. The patch command is used to apply such patches (see man patch and man diff for more info).

The tarball also includes a dkms.conf file to make it work with dkms.

It does not include the /usr/share/X11/xorg.conf.d/50-synaptics.conf file changes to control the jumpy cursor. You have to do those yourself.

The 10.10 announcement went out and I note that this bug is not in the list of known issues. Considering other things listed there I'd say this one is well qualified. If I was running Lucid and upgraded, I'd be pretty annoyed at running into this regression and having to spend significant time looking for and implementing the workaround. Knowledge of this regression is valuable information to deter upgrade until it is solved.

The patch fixes the problem for me (HP Probook 4520s, Synaptics Touchpad, model: 1, fw: 7.4, id: 0x1e0b1, caps: 0xd04771/0xe40000/0x5a0400)

The patch also fixes the problem for me (HP Mini 210-1030BR, Synaptics Touchpad, model: 1, fw: 7.4, id: 0x1e0b1, caps: 0xd04771/0xe40000/0x5a0400), although I can't seem to learn how to enable true multitouch.

With patch it's working better, but Synaptics Touchpad, model: 1, fw: 7.4, id: 0x1e0b1, caps: 0xd04731/0xe40000/0x5a0400 with tapping makes two clicks instead of one.

Alright, so how do I install this patch? I've been asking around on the
Ubuntu Forums and the like and haven't gotten a response, I just want it to
function as it did in 10.04 if that's possible

Hi all,

I wanted to give everyone here a heads up on Synaptics ClickPad support in Linux in general. On Friday, Oct. 8th, I sent some patches to enable multitouch features for Synaptics touchpads to the upstream X and Linux mailing lists. This sparked a wide ranging discussion on how to go forward with Synaptics support. A lot of the issues with ClickPad devices may be resolved with proper multitouch support.

If you are interested, you can follow the discussion and contribute at http://www.spinics.net/lists/linux-input/ and http://lists.x.org/archives/xorg-devel/2010-October/thread.html.

Thanks!

Chase: This is a bug tracker, not a discussion forum. Please stick to the bug at hand.

pauls dkms module fixed this problem for me.

It also fix Bug 612591 (which may be a duplicate of this bug).

What more is missing before an official update appears?

Thx for your work here Chase (and also thanks to Takashi)
I'm trying to compile psmouse with your patches to give it a try.
Have you any rep. to download the full set of diffs to test?
Glad to see that there are work to fully support clickpad features.

I have applied paul's patch and now I am able to right click and middle click. even then the experience is not great at all and its mostly a hit and miss thing. Right click can be a pain most times I have to initiate the action like 3 times before it registers if the mouse doesn't jump around, it would open the context menu initiated by the right click and the context menu closes almost immediately. I have to continue the right click action before I get it right. Same thing for middle click. Most times middle clicking also initiate left click actions, like if I try to open a link as tab with middle click the link gets open as tab and also because left click action is taken the link also gets open within the current page am viewing. I don't know if anyone else have this issue or its just me? hp probook 4420s here

bigbrovar, sounds like you failed to set the jumpy options in post #49. Also, open a terminal and do "man synaptics" and "man synclient" and learn how to adjust the time to simulate middle clicks to make it more workable. It's trial and error, but eventually you can make it work.

hth

Using dkms to build the psmouse module works for me. Thanks, pauls.

I am using a netbook HP Mini 210.

Thanks pauls, worked for me as well

Can confirm that the patched kernel module fixes right clicking for me, I have a HP Envy 15 first gen.

The patched kernel module fixes right click issues, but does anyone know how to enable click and drag operations? Every time I set a second figure down on the clickpad on my HP 210, the cursor jumps position This is something which openSUSE did fix in their patch and the subsequent update that was issued. It went a long way towards full functionality for the clickpad on the 210.

I can confirm the fix working on an HP Touchsmart tm2-1090eg notebook.

The jumpy cursor problem is a matter of configuration as far as I know. Use "synclient" to see what values are used in openSUSE and Ubuntu and try them out. Setting "JumpyCursorThreshold" to 100 worked well for me.

I have a HP Touchsmart tm2-1090eo. The fix works, sort of. Right-click works, but sometimes only on the second click. Left-click does not work, althoug tapping does. So I now have both buttons, sort of.

I'm using a dm3 which also uses the synaptics clickpad input. I've applied pauls patch and I have to say it has improved things quite a bit.

Its still flawed however. Namely the right click only applies to a very small corner of the designated (as marked on the clickpad) right click zone and if you have tap to click enabled tapping this area will leftclick except for the very very very bottom most corner

This means that if I lets say right click on the desktop 9/10 I will instantly create a new folder as this is read as a right click instantly followed by a left click even though it is in fact just one right click

The strange thing is that 10.04 had much better behavior in this regard, and that the implementation in openSUSE (which I use on another similar laptop) trumps all. Would it be possible to see what the openSUSE guys are doing and copy that here? On openSUSE right clicking is very responsive has no conflicts with tap to click and the clickpad can be turned on and off by tapping the dot on the top left corner as indicated by the LED there.

I have a similar problem after upgrading from 10.04 to 10.10 on my Samsung NB28 laptop. Left and Right buttons work in Firefox but not on the Desktop or Workspaces.

Same problem on HP 210 - 1014TU

Same Problem with Lenovo 10-3 fixes tnx to Pauls instructions. Thank You Paul!

Again Pauls instructions modified for people who are not so familiar with working with the Terminal:

## Pauls Original
#$ My Comments

## It's possible to use dkms to build the psmouse module for the buttonless synaptics touchpad on some newer netbooks.

## First make sure dkms package is installed.

#$ To check, type:

dpkg --list | grep dkms

#$ If this does not give any result, type

sudo apt-get install dkms

## Next download this patched source archive for the psmouse module from kernel 2.6.35-22-generic on maverick. I just posted it to this bug, it's called: psmouse-2.6.35-22-generic-patched.tar.bz2

#$ Just to keep order make a directory somewhere, type

mkdir touchpad
cd touchpad

#$ To download, type

wget https://bugs.launchpad.net/ubuntu/+source/linux/+bug/582809/+attachment/1675262/+files/psmouse-2.6.35-22-generic-patched.tar.bz2

## In a terminal, unpack the source archive in /usr/src

#$ To do this, type

tar -xjf psmouse-2.6.35-22-generic-patched.tar.bz2
sudo cp -r psmouse-2.6.35-22-generic /usr/src/

## Next, in a terminal, enter these commands:

sudo dkms add -m psmouse -v 2.6.35-22-generic
sudo dkms build -m psmouse -v 2.6.35-22-generic
sudo dkms install -m psmouse -v 2.6.35-22-generic

## This should install the psmouse.ko module in /lib/modules/<kernel version>/updates/dkms. Reboot to load it.

#$ --- !!! --- On my Lenovo, This was all I had to do to make the right an left mouseclick work again, which is all I need to be happy (I don´t need 2-fingers-whatever ...)

## If the mouse doesn't function properly, use this command to check if it's installed.

sudo dkms status -m psmouse -v 2.6.35-22-generic

## If it's not, then try rebuilding it with

sudo dkms build -m psmouse -v 2.6.35-22-generic
sudo dkms install -m psmouse -v 2.6.35-22-generic

## Once a new kernel is issued with a fix, then you can remove it with:

sudo dkms uninstall -m psmouse -v 2.6.35-22-generic
sudo dkms remove -m psmouse -v 2.6.35-22-generic --all

## I also believe that dkms will automatically build and install it on any kernel upgrade, but haven't tested that yet.

## After installing any kernel update, you can test with

sudo dkms status -m psmouse -v 2.6.35-22-generic

## and if it's not built, use the above commands to build and install it.

## Reboot to make it effective.

## For more info, see man dkms for the official documents.

Did someone tried this:

http://aur.archlinux.org/packages.php?ID=38120
?

It seems that an user on ARCH linux successfully makes things working fine...

@tob
I've tried the workaround in #60/61 by Pauls
but I'm still experiencing problems with my touchpad,

If I run:
   dmesg | grep -i synaptics
I got:
   [ 19.998702] input: PS/2 Synaptics TouchPad as /devices/platform/i8042/serio4/input/input9

Should I have to install also your aldo synaptics.diff or is not necessary after the workaround from Pauls?

Sorry for posting again...
I forgot to post the output of :
      synclient -m 100
Can't access shared memory area. SHMConfig disabled?
Couldn't find synaptics properties. No synaptics driver loaded?

Is that normal?

I'm running Ubuntu 10.10 with the last Kernel 2.6.35-23 but I have tried it on -22 with the same problem.

@Davide
Pauls applied my diff and posted the patched source with instructions on how to compile it using dkms. Therefore there is no difference between applying my diff yourself or using Pauls instructions.

It doesn't look like the Synaptics xorg input driver is being used for your touchpad. Did you follow the instructions that eSe provided in post #54 to add a line to your /etc/modprobe.d/psmouse.modprobe file? Did you modify your xorg.conf file? Did you modify your 50-synaptics.conf file?

You need to add Option "SHMConfig" "on" to your 50-synaptics.conf file for synclient to work (see post #49). However, synclient won't work if the Synaptics driver is not being used for your touchpad.

OK now this is the output of:
      # dmesg | grep -i synaptics
[ 135.770279] Synaptics Touchpad, model: 1, fw: 7.4, id: 0x1e0b1, caps: 0xd04771/0xe40000/0x5a0400
[ 135.770285] Synaptics: Clickpad mode enabled
[ 135.807505] input: SynPS/2 Synaptics TouchPad as /devices/platform/i8042/serio4/input/input13

@tob What do you mean for?
"Did you modify your xorg.conf file"
I modified the file 50-synaptics.conf a suggested... Is that what you mean?

@tob
Actually the right click works fine, after reboot, and I'm able to run synclient -m 100

BTW I'm still not able to get recognized more than one finger on my touchpad... I've tried also with emulation as you suggested in #72 but without any good result.

Do you know other more specific fingers recognition bugs open?

@Davide
You can ignore my previous questions because it looks like the Synaptics driver is working properly with your touchpad now. Can you share what you did to resolve the problem? It might help someone else with the same problem.

2 finger emulation is the best that you are going to get without multitouch support. Try to use the synclient to determine the best values for the following options in your 50-synaptics.conf file:
Option "EmulateTwoFingerMinW" "5"
Option "EmulateTwoFingerMinZ" "90"
The W and Z values should both change a little bit when you add/remove the second finger. Try to determine good threshold values for W and Z to use in your 50-synaptics.conf file.

Following the instructions as graciously compiled by Johanna in comment #94 has restored the right button functionality on my Hp Pavilion dv7-4073nr under Ubuntu 10.10 (which disappeared when upgrading from 10.04 like others have noted). I still have random movements as my palm brushes the pad, but at least I am not going insane trying to press the right button on a tiny area at the corner. Thanks to all for the work on this!

I find a jumpy cursor value of 250 works well for me on this model.

Also, for those like me that don't have SMHConfig on, I can test changing configuration values on the fly with commands like:

xinput set-int-prop 'SynPS/2 Synaptics TouchPad' 'JumpyCursorThreshold' 8 200

The 8 is the size of the 200 value, and the appropriate values and options can be gleaned from the man page of synaptics.

@Tob
It seems that my problem was an old file in the /etc/modprobe.d/ dir different from the one suggested in the other comments, but that anyway had some call to psmouse.
   For people like Richard that still have problem switching on SMHConfig, I suggest to check all the file and comment-out/remove all the psmouse related row.

Is there a way for reducing the area of the touchpad to make sure that an area will be restricted for the buttons and not also for the touch area.

I still have some problem clicking with the right button, since the threshold is too short and as soon as I click my finger moves just a bit and the window that usually appears after the right click, immidiately dissapears. And sometimes it doesn't appear at all...

This is really frustrating...

@Davide
"Is there a way for reducing the area of the touchpad..."
Yes, in fact my original patch disabled the button area just like Ubuntu 10.04. Assuming that you used Pauls instructions in post #61, try this:
open /usr/src/psmouse-2.6.35-22-generic/src/synaptics.c with a text editor.
search for and delete the following line: "if (hw->z > 77)".
Enter the following commands into a terminal:
sudo dkms build -m psmouse -v 2.6.35-22-generic
sudo dkms install -m psmouse -v 2.6.35-22-generic
sudo rmmod psmouse && sudo modprobe psmouse

"This is really frustrating..."
I agree. I think the problems that you described are due to issues in the xorg input synaptics driver. Hopefully they will be sorted out by Ubuntu 11.04. I use a 2 finger click for right click instead of the physical buttons which works very good. I have also gotten used to dragging by using the double tap-drag technique instead of click and drag. This way I can avoid using the physical buttons all together. There has been some nice work on a true multitouch solution for the synaptics touchpads, and I hope that it makes it into the next version of Ubuntu.

@Tob I've tried your fix, but I did't find any effort from that...
The right click is always hard, and the touch area was not changed...
I would like to limit the touch area to a smaller rectangle compared to the real one.

I am on Ubuntu 10.04 and fixed the area problem by changing the
YMIN_NOMINAL define to 2000.

I picked that number after experimenting with synclient and seeing that
the button area ends something around 500 points from the bottom y point.

You can also use synclient to set "AreaBottomEdge" to a value other than 0 (somewhere between the values of "BottomEdge" and "TopEdge"). That way You don't need to modify the source and recompile. synclient is in xserver-xorg-input-synaptics.

@Frederick
Thanks you very much... That was exactly what I need

I found this the value that fits my HP tm2 2000 touchpad area with this:
 $ synclient AreaBottomEdge=3700
And make it permanent by adding this line to my synaptic.conf file:
                   Option "AreaBottomEdge" 3700

And that's it...
Thanks again, know I can finally enjoy my touchpad.... Only the multifingers recognition is still missing..

Is this bug related to 636720? I have re-installed 10.04 as 10.10 simply has too many problems (at least for HP Pavilion Laptops) and regressions. 10.04 offers the same functionality without most of the problems.

Same problem here with Maverick on a HP Mini 210. I got right-click working - still not ideal, but acceptable - by installing the driver xserver-xorg-input-synaptics_1.2.2-2ubuntu5eyre1 from here: http://sites.google.com/site/andyeyre/files .

There is a new patch for this bug in the upstream kernel at https://bugzilla.kernel.org/process_bug.cgi

I have created a new dkms archive with this patch and am successfully testing it on my lenovo s10-3t. If you wish to try it, you can uninstall the existing dkms module and delete the archive:

paul :~$ sudo dkms remove -m psmouse -v 2.6.35-22-generic --all
paul :~$ sudo rm -fr /usr/src/psmouse-2.6.35-22-generic/

Next, download and unpack this archive into your /usr/src
paul:/usr/src$ sudo tar cjvf psmouse-2.6.35-23-generic.tar.bz2

Use dkms to add, build, and install:

paul :~$ sudo dkms add -m psmouse -v 2.6.35-23-generic
paul :~$ sudo dkms build -m psmouse -v 2.6.35-23-generic
paul :~$ sudo dkms install -m psmouse -v 2.6.35-23-generic

Then reboot and the new module will work. I also need to use synclient:

synclient HorizEdgeScroll=1 to enable horiz scrolling
synclient JumpyCursorThreshold=250 to be able to select and copy text

Those of you good with command line know I made a mistake with my last post, but for those not, change

paul:/usr/src$ sudo tar cjvf psmouse-2.6.35-23-generic.tar.bz2

to this:

paul:/usr/src$ sudo tar xjvf psmouse-2.6.35-23-generic.tar.bz2

Thanks for the new patch pauls.

I applied the new patch to test it.

But now the left and the right button are not working any more.

So I think I'll go back to the old patch.

Is there something I can do about that?

Thanks!

I'm seeing the same thing. I'll be undoing some of the earlier patches to see if that helps. Also, if someone could post the bug # or git commit from bugzilla.kernel.org referenced earlier, that would be appreciated.

I think pauls is referring to this bug:
https://bugzilla.kernel.org/show_bug.cgi?id=18122

This patch does not change the operation of the touchpad, it only fixes the Clickpad detection. Apparently some touchpads are being incorrectly detected as Clickpads. Therefore, the only people that will benefit from this patch are people that don't have Clickpads. With that being said, this patch can be safely applied along with the other patches that I posted earlier.

I have to take back what I posted earlier. It looks like the patch doesn't work properly. It completely breaks the Clickpad detection.

I copy here the text (i've also make some modifications) from an offtopic report by me in the multitouch bug #308191

I don't know if I should report this here or in the clickpad buttons bug
https://bugs.launchpad.net/bugs/582809

I've tested the 1.1.0 package, and it compiles Ok and works of for two finger scroll and three finger paste.
But with clickpads, you cannot click+drag, because as they have a full sensitive surface with no physical separated buttons,
when you press the touchpad with a second finger to make the click, the driver detects two fingers and so, stops the cursor and start scrolling. Same happens if you made a click, and with the finger pressing the surface (in button area) you put another finger to drag the thing below the cursor.
Testing Win7 synaptic driver behaviour, it seems that it takes into account the delay or time between the first finger and the second finger touchs. i.e.,
If you put two fingers in the touchpad more or less simultaneously, it behaves as two finger detected and start scrolling, but
if you put first one finger, and then the second finger with some delay (~0.5s or more), cursor moves as if only one finger was detected, and so, you can click and then touch and drag. Same if you are moving one finger on the touchpad (moving the cursor) and then touch with other finger to do a click for example, the driver behaves as if only the initial finger was over the touchpad, allowing you to click with the other.
In fact, it seems that Win7 syn. driver doesn't use the area marked as left buttton so much. You can click+drag or move+click or scroll with two finger simultaneously in any place. The main diference is when you make the click in the right-bottom area designated as right button, as then behaves as right click.
MacBook buttonless clickpads, have no marked area for left and right button, and so, left button works as stated before in Win7. Right button has the difference, and is triggered only if you press right-bottom area of touchpad (more or less the same as Win7 but with a greater area for W) and if you make the click with two fingers on pad. Triple click would work with three fingers clicking simultaneously over the pad.
This last behaviour (Mackbook) is very intuitive and could avoid to define the marked areas that differ between touchpads, making it a more universal solution for clickpads.

I'm sure that i've not stated anything new here, but just for knowing your opinion...

@pauls is there a way to get your patch to work with 2.6.37 kernel? I tried installing it there but installation failed

This is possible to provide pauls-patched psmouse in deb package or PPA?
For example there is already available deb-package with multitouch support: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-synaptics/+bug/308191 (#167).

after

sudo sh -c "echo options psmouse proto=exps > /etc/modprobe.d/psmouse.modprobe"

I have no touchpad tab under system-->preferences-->mouse

Can anyone help me?

I'm having problems with the clickpad in Natty with an HP Pavillion DV7-4263CL I'll include what works in case there was a feature I didn't think of or know about to test:

1) Normal mouse movement - no jitters or jumps
2) Left clicking with the clickpad button
3) Side scrolling
4) Two-finger scrolling

What doesn't work:
1) Right clicks - clicking on the right button just does a left click
2) Dragging - if I click and hold the left button and try to drag a window, the right-click context menu pops up

Current version of xserver-xorg-input-synaptics is 1.3.99+git20110116.0e27ce3a-0ubuntu4

If it matters, the dragging works in Debian Sid but right clicks still don't with version 1.3.99.901-1.

I set the AreaBottomEdge variable with synclient but that had no effect.

I'm having the same issue with a HP Probook 4520s and Natty. It's a shame, but the clickpad works like a charm on OpenSuse 11.4 RC2. Please, could anyone have a look at OpenSuse 11.4? What did they change so that clickpads work so flawlessly? Unfortunately, my developer-skill are extremely poor, so I can't look up that information myself.

It would be really embarassing, if clickpads worked under OpenSuse 11.4 but not under Ubuntu 11.04. Why? Because both are linux and it's all open source! Why can't just Ubuntu copy the necessary part from OpenSuse?

Natty - daily build 1 March, i386 Desktop ISO - exhibits this problem on a HP Mini 210.

Works:

1. Left Click
2. Edge Scrolling
3. Double Tap to drag (shift+click equivalent)

Not working:

1. Right Click
2. Shift+Click to drag - the window frame outline appears briefly but is then lost

Odd behaviour:
1. Click+Tap: opens context menu (like right click). When the finger is release, both left click and right click actions take place.

I have an HP dm1z with the same issue.

On th0min4tor's suggestion, I took a look at OpenSuse's sources, and they have a number of patches for fixing clickpad issues and adding functionality: https://build.opensuse.org/package/files?package=xorg-x11-driver-input&project=X11:XOrg
If I get some time this week, I may try building with these diffs to see if I can get things working under Natty.

Ideally, it would be nice if these patches made it upstream so all can benefit.

OK so I have an issue on Natty with an Acer Aspire One touchpad not working. I'd logged it as an xorg issue https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/730823 but the more I look into it I think it may be related to this kernel driver issue.

I just purchased an HP Envy 17" laptop with a Synaptics clickpad and I have the same issue. Pointer movement is erratic, especially when clicking and dragging, right mouse button area does not work.

I've got an HP Pavilion 6, and have had luck patching the xf86-input-synaptics-1.3.0 driver. Anyone running Gentoo can use these <http://preview.tinyurl.com/4l69fe7> instructions, which worked out-of-the-box for me.

For everyone else, patching xf86-input-synaptics with the attached patch should fix things. I've had left, middle, and right click working flawlessly, as well as two-finger scrolling and (slightly dodgy) dragging.

@Ryan Gray

Can you tell me how to apply this patch?

*I must say, I tried opensuse 11.4 and touchpad works great there. No luck yet on maverick.

Here is a patch based on the patch by Takashi Iwai (https://build.opensuse.org/package/view_file?file=xf86-input-synaptics-add-clickpad-support.diff&package=xorg-x11-driver-input&project=X11%3AXOrg&srcmd5=17f381a34750c8d6634d00015d210d0c).

It is updated to the version of xserver-xorg-input-synaptics in Natty (git20110116).

I changed a section that removed sensing from the button area.

First off, excuse my ignorance.

What source should the patch in comment #129 be done against. In the past, I've used "apt-get source" to get the source but that gets the git20110116 directory not the 1.3.0 directory mentioned in the patch file.

After editing the patch (from comment #129) to reflect the correct directory, it wouldn't apply cleanly. It also then wouldn't build with dpkg-buildpackage; one of the other patches that gets applied during that process subsequently failed.

I ran into these problems during my attempt to adapt the OpenSUSE patches (against xf86-input-synaptics-1.3.0) to the version in Natty. Just adding support for the clickpad is one thing. There are a number of patches from OpenSUSE that provide better support for click-and-drag, and detect and enable led tapping to enable/disable the clickpad. After many hours adapting the the patches, I was finally able to get the package to build, but it didn't seem to make any difference. I'll keep trying in my spare time, but it would be helpful if someone more knowledgeable than I with regards to X input drivers take a whack at it.

My attached patch was added to the right of the screen, it was _not_ the link I posted. The patch can be found here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/582809/+attachment/1906642/+files/clickpad-1.3.99%2Bgit20110116.0e27ce3a-0ubuntu7.patch

To use it, do the following:
- get the source using apt-source (apt-source xserver-xorg-input-synaptics)
- put the patch file in the xserver-xorg-input-synaptics-*version*/debian/patches/ folder
- add the file name of the patch to the xserver-xorg-input-synaptics-*version*/debian/patches/series file
- get the programs needed for building the package (sudo apt-get build-dep xserver-xorg-input-synaptics)
- change the working directory to the xserver-xorg-input-synaptics-*version*/ dir
- build the package (dpkg-buildpackage -b)
- install the package (sudo dpkg -i ../xserver-xorg-input-synaptics-*version*.deb)

Hugo,

I went through and got the git source of xserver-xorg-input-synaptics-1.3.99+git20110116.0e27ce3a from the Natty AMD64 repositories (I'm on Maverick). I downloaded your patch, added it to the series file, and built the dependencies. When trying buildpackage, the patches all seem to go on fine, but make dies after a while with this error:

In file included from ../../src/eventcomm.c:32:
../../src/eventcomm.h:49: error: ‘ABS_MT_DISTANCE’ undeclared here (not in a function)

I've looked around with grep and I don't see any declaration of such a variable, so make seems correct. Aside from your patches, I have only the default patches in the patches directory. Any ideas?

Hi Paul,

You should get the source files for the version of the synaptics driver that is in Maverick (1.2.2). You can do this by running 'apt-get source xserver-xorg-input-synaptics'. The newer version is not compatible with your kernel.

I attached a patch for version 1.2.2 (on the right side of the page, under the subscribers). It compiles cleanly here, but I did not test it.

Hugo,

1. Does this patch allow you to click and drag cleanly using the clickpad?
2. Do you know if it is compatible with the multitouch psmouse patch from #308191?

Thanks!

Roman,

1. It does not fix click and drag. There may be a patch at https://build.opensuse.org/package/files?package=xorg-x11-driver-input&project=X11%3AXOrg&rev=17f381a34750c8d6634d00015d210d0c that fixes it, but I don't have time the coming days to look at it.
2. I don't know which patch you mean, but it probably will, as the patch is quite small.

Thanks. I had tried compiling 1.3.0 SUSE version directly with some of these patches on maverick, but was not able to solve this click and drag problem. Overall, I still prefer the multitouch fix from #308191 (you can search with 1.1.1 to find the right package): it allows right clicking by tapping with 2 fingers. Hope the click and drag will work by the time natty is released

Right clicking by tapping with 2 fingers already works in natty. Click and drag works with the left button by double tapping, but not by clicking and dragging.

I can confirm that 2 finger tapping does indeed send the right click message. Also, for me at least, the may to get dragging windows to work is to hold down Alt while double-tapping, however, don't let the second tap go. It's really 1.5 taps.

However, this is not an adequate fix for dragging because it only allows you to drag a window around and not an item, such as a folder in Nautilus

HP has released Linux drivers for these clickpads, for example for HP ProBook 4320s, which I own. But these are drivers for SUSE Linux, in .rpm packages. I wonder if there is a way to port them into Ubuntu? Anyone would be able to do it?
I mean, if the drivers are already provided for one Linux distro, there should be some way to apply them into another distro.

The tap+drag also works in nautilus. Of course, for standard tap+drag, you don't need to hold Alt. Alt is just the modifier in for moving a window by dragging the mouse.

Some of the issues may be the result of the new click pad functions not being well documented yet.

With Natty on an HP Envy, the following work:

One-finger tap => left click
Two-finger tap => right click (context menu)
Three-finger tap=> Middle click (e.g. insert text)
Two-finger drag => scroll up / down (or left/right) (enable via mouse settings)
Tap + drag => click and drag (i.e. drag and drop)
-- Works for e.g. moving windows when when also holding Alt
Alt + three-finger tap + drag => resize windows (equivalent of Alt+middle drag on a 3-button mouse)
(It's actually sufficient to initiate the tap with three fingers and do the dragging with just one finger.)

LordBarman,

Suse Linux 11 is using 2.6.32 kernel, Ubuntu is using more newer versions of kernel(10.10 - 2.6.35) and HP has buillt only i386 package, there's no AMD64 drivers.

I've taken the SuSE patches which add clickpad functionality to the x.org synaptics driver and ported all of them to the Ubuntu xserver-xorg-input-synaptics package (the version currently in Natty).

The result is pretty promising, though I'm doing it to make my wife's HP Envy laptop usable and I do not use the laptop on a daily basis, the basics like click-and-drag, etc, seem to be working (don't ask me about multi-touch, gestures, etc).

A tarball of the patches is here (they are as similar to the SuSE patches as possible, 212-fixups.patch contains the additions to make the result compile cleanly):
http://david.hardeman.nu/synaptics-suse-patches.tar.bz2

To build your own xserver-xorg-input-synaptics package, do:

mkdir tmpbuild
cd tmpbuild
wget http://david.hardeman.nu/synaptics-suse-patches.tar.bz2
apt-get source xserver-xorg-input-synaptics
cd xserver-xorg-input-synaptics-<version>
cd debian
cd patches
tar xfvj ../../../synaptics-suse-patches.tar.bz2
ls -1 2*.patch >> series
cd ..
cd ..
sudo apt-get build-dep xserver-xorg-input-synaptics
dpkg-buildpackage -us -uc -rfakeroot
sudo dpkg -i ../xserver-xorg-input-synaptics_<version>_<arch>.deb

And then restart your X server

Left as an exercise for the reader:

You can also build a custom version of the psmouse kernel driver with support for the clickpad enable/disable led using another SuSE patch available here:

https://build.opensuse.org/package/files?package=kernel-desktop&project=openSUSE%3AFactory
File patches.drivers.tar.bz2, patch input-Add-LED-support-to-Synaptics-device

The result seems quite crash-prone though

Tried your patch on Natty. The right click functions properly now, and two finger scroll still works. But click and drag doesn't seem to work. And, how hard would it be to make it so that any touch on the button area (below the little bar) to not allow any mouse motion? Hopefully the Suse patches will eventually include support for doing the double tap in the upper left corner to disable the clickpad (and light the led).

BTW, in your instructions, the "ls -l 2*.patch >> series" command doesn't quite work right. It adds a bunch of extra information to the series file. Just add them manually.

Thanks!

Hi Paul,

You can mask out an area of the bottom of the touchpad by using the "AreaBottomEdge" option. Add the following to /etc/X11/xorg.conf (create it if needed):

Section "InputClass"
        Identifier "Synaptics With Bottom Area"
        MatchIsTouchpad "on"
        MatchDevicePath "/dev/input/event*"
        Driver "synaptics"
        Option "AreaBottomEdge" "4100"
EndSection

Replace the value for AreaBottomEdge with whatever works best for your trackpad.

Thanks for that tip Chase. I messed around using synclient and 4100 works great for me too. By doing that, click and drag functions nearly perfectly as well. However, I loose the right physical click feature introduced by David's patches. Right click still functions if I tap with two fingers in the main clickpad area, but I liked having the physical click like with the left click.

Any ideas?

Argh, cannot edit my post. I wanted to add that even with the AreaBottomEdge setting enabled, there's still an annoying problem:

By setting that parameter, you can put your finger in the area below that value, and by moving your finger, it won't move the mouse pointer. That's good. However, if I put a finger in the good area (the area intended to allow for mouse pointer movement) and just hold it there on the clickpad, then all of a sudden, dragging around a finger (while still having that first finger contacting the good area) in the area below the AreaBottomEdge causes the mouse pointer to move again (but only horizontally).

I hope that makes sense...

paul:

1)
my instructions said
"ls -1 2*.patch >> series"
you did
"ls -l 2*.patch >> series"
(hint: it might take some squinting to spot the difference) :)

2)
As for double-tap on led to enable/disable, it is already supported with the SuSE patches, the problem is that it needs a small kernel patch as well (the patch I mentioned at the end of my post).

Hi David Härdeman,

Thanks for SuSe patches. On HP 4320 d&d(with disabled two-fingers scroll) and right button works fine.

I've patched psmouse for 2.6.38-7, but LED doesn't work by double tapping on it.

 Synaptics LED (288): 0
 Synaptics LED Status (289): 0
 Synaptics LED Dobule Tap (290): 1

Did you change smth in a LED patch?

Alexander:

Could you check if you have a file named "psmouse::synaptics" somewhere under /sys?

find /sys -iname "psmouse::synaptics"

It seems that the SuSE patch to psmouse has a hardcoded list of supported hardware which might not include yours...

David ,

There is no psmouse::synaptics file.

Please, show me your `dmesg | grep Synaptics` output.

Alexander,

I'd need to first find the time and then take the laptop from my wife long enough to recompile and reload the psmouse driver, so it'll take some time to get you some dmesg output.

Meanwhile, if psmouse::synaptics isn't showing up, there's only three reasons I can think of:

a) You're not loading your patched psmouse module

b) The MOUSE_PS2_SYNAPTICS_LED option wasn't set when you compiled it

c) The patched module fails to recognize your hardware as LED-capable (which isn't unlikely given some of the comments in the patch)

What you could do is first to remove these lines from the SuSE patch:

+#ifdef CONFIG_MOUSE_PS2_SYNAPTICS_LED

and

+#else
+#define synaptics_init_led(ps) 0
+#define synaptics_free_led(ps) do {} while (0)
+#define synaptics_sync_led(ps) do {} while (0)
+#endif

Then try sprinkling a few printk's around the LED detection in psmouse. I'd suggest you add

    printk(KERN_INFO "synaptics: checking for LED control\n");

just before

    if (!priv->ext_cap_0c || SYN_CAP_PRODUCT_ID(priv->ext_cap) != 0xe4)
        return 0;

in synaptics_init_led()

That way, you'll get a message when LED detection is attempted and another one if successful.

If you only get the first message, the detection fails, you could then try to hardcode it by commenting out the above two lines in synaptics_init_led().

Hi,

I haven't had much experience with Ubuntu, but at the moment I'm trying to get my girlfriends HP Probook 4320s's clickpad to work.

I tried Davids patching solution but got stuck with 'dpkg-buildpackage -us -uc -rfakeroot'

Aadu:

Which version of xorg-input-synaptics in your system?

http://ompldr.org/vOGRtNQ/xserver-xorg-input-synaptics_1.3.99+git20110116.0e27ce3a-0ubuntu11_amd64.deb

I've built deb for Ubuntu 11.04 AMD64 with David's patches. On next week I will try to test led on 4320s.

Alexander:
That file fixed everything!

My HP Pavillion dv6 qte is finally acceptable under Ubuntu 11.04 using this patched deb.
I have a question though: would you consider putting this up in a PPA? I've heard that the new Launchpad Recipes can pull, patch, and build some packages for you (maybe I'm wrong on the patch part).

Again, I thank you and David a whole bunch!

David,

I don't know where I need to set MOUSE_PS2_SYNAPTICS_LED option for dkms module, but I commented out definitions of this option and built psmouse package. Thanks.

http://ompldr.org/vOGV6cg/psmouse-dkms_2.6.38-7-generic_all.deb

I just wanted to add that I followed David's instructions in post #144 and now my clickpad is working as expect on a HP Mini 2102 (same as a 210 model). Thank you very much!

Hopefully that patch makes it into an official release soon.

Will the fix show up as a normal update?

Yes, I would love to know when. I've been trying to get my touchpad fixed on my HP mini 210 1140NR netbook for a few days now...

Does fix also include support for the clickpad enable/disable led (as suggested patch at comment #144) ?

Does somebody knows if there is any way to make changes in synaptic's code, compile and test the changes without making dpkg-buildpackage -us -uc -rfakeroot and then sudo dpkg -i ../xserver-xorg-input-synaptics_<version>_<arch>.deb

Thanks in advance!

I have dv6 running 11.04 64bit. I am not able to right click anymore in ubuntu is there a solution to this right now. Can anyone provide a step by step to get it to work..

@Jordan, try 3 finger tapping. After I installed the patch, right click was working, but after an update from the repository, 2 finger tapping is a middle-click and 3 finger tapping is a right-click.

I wanted to add that the patch in comment #144 worked perfectly on an HP Pavilion dv7. Thanks!

hi I have hp pavillion dv6-3141ea. I just installed 11.04 64bits on my brand new laptop. The right click only works when i tap with two fingers (not when i click right button). I tried installing the amd64 deb file, #155 above, on my system. Ubuntu software centre complains that a later version already installed - so cannot install. Is there a way to enable right click on clicking right button.

I also cannot select a portion of text by clicking left button and dragging.

I can't do this either. The double-tap to drag function is very iffy here on
my HP DV7

An upgrade to xserver-xorg-input-mouse was released and it broke my mousepad right click. I have version 1:1.6.0-1ubuntu3 now.

hi,

@ amsri
@ BirdDog

i, using ubuntu 11.04 with latest updates, but didn't install any patch.

my clickpad works with following settings:

AreaBottomEdge=4331
TopEdge = 0

i put these options in the file, which has to be created:

/usr/share/X11/xorg.conf.d/52-synaptics-quirks.conf

with content:

Section "InputClass"
 Identifier "HP Clickpad"
 MatchIsTouchpad "on"
 MatchDevicePath "/dev/input/event*"
 Driver "synaptics"
 Option "AreaBottomEdge" "4331"
 Option "TopEdge" "0"

greetings

I installed the latest xserver-xorg-input-synaptics update from the Update Manager and it broke the right-click and left-click/drag functionality implemented by Comment #144 patches. I was able to re-install the patch from the .deb file I had built by going into the tmpbuild directory and typing sudo dpkg -i xserver-xorg-input-synaptics_1.3.99+git20110116.0e27ce3a-0ubuntu12_amd64.deb

I was able to fix the right click again using the same fix as @belltown.

Thanks David Härdeman. It works for me with my HP mini 210. Just a problem : I can't select text with the left click. Can you explain how I can compil psmouse-dkms ?

@belltown did'nt you need to to uninstall the later version first. Or you just ran the command you mention in #172 and the package got automatically downgraded. I was worried that running your command would install an additional (previous version) and the both the previous and later version would conflict. Does the older version allows you to select text and drag using left button.

@amrsi
I think all I did was run the dpkg -i command again (Comment #174). Previously, I had applied the patches from Comment #144, but then they were overwritten when I installed the latest xorg synaptics driver from the Update Manager. Everything now seems to be working the way it was after I had initially run the Comment #144 patches. right-click works, as does left-click to select and drag.

@belltown thanks for reply. I ran the command with the deb file posted in #155 above and it replaced the later version with the with one in #155. I am now able to right click , select text and drag and drop. Hopefully we receive a newer update soon which includes this fix along with the fix which was contained in the version I just replaced.

For building latest synaptics package:
    - sudo apt-get build-dep xserver-xorg-input-synaptics
    - apply patches from SuSe
    - dpkg-buildpackage -b

After that install custom package:
    - dpkg -i ../xserver-xorg-input-synaptics-[ur package version].deb
    - echo xserver-xorg-input-synaptics** hold | sudo tee dpkg —set-selections # prevent package upgrade

For dkms(It's not good idea for using enable/disable touchpad, cuz sometimes kernel crashes):
    - get kernel source by apt-get
    - make dir smth like /usr/src/psmouse and copy /usr/src/linux-source-[ur version]/drivers/input/mouse to it.
    - make file dkms.conf:

PACKAGE_NAME="psmouse"
PACKAGE_VERSION="____ur kernel version_______"
CLEAN="rm -f *.*o"

BUILT_MODULE_NAME[0]="psmouse"
MAKE[0]="make -C $kernel_source_dir M=$dkms_tree/$PACKAGE_NAME/$PACKAGE_VERSION/build/src psmouse.ko"
BUILT_MODULE_LOCATION[0]="mouse"
DEST_MODULE_LOCATION[0]="/updates"

AUTOINSTALL="yes"

    - sudo dkms add -m psmouse -v [ur kernel version]
    - sudo dkms build -m psmouse -v [ur kernel version]
    - sudo dkms install -m psmouse -v [ur kernel version]

When I follow the instructions on my HP DV7, I come back and only taps work
on the touch pad. No right-click and no left-click. If I go to Touchpad in
System Settings, it says "no touchpad found". So, nothing can be configured

Thanks Alexander S. Gryanko. I install psmouse dkms but the LED doesn't work.

Any idea ?

If I use one finger for scroll, I can select text with the left click.

@Mohegan:

Remove #defines from patch as David describes in #153, but sometimes kernel will crash

Thanks. It 's work but only when I tape with the keyboard. How can I deactivate the touchpad with a double tap in the top left corner ?

After several tries, disabled touchpad works but if use the keyboard, the led shutdown and the touchpad works again.

Any idea how can I use the both functions "disable touchpad while typing" and "touchpad off by double tap" ?

Have the same error as comment #154. Does .deb given in comment #155 work on ubuntu 10.10?

I don't think this is fixed in 11.04. I have a HP-dm1 and selecting text was impossible (except by double-clicking). I followed the instructions here: http://ubuntuforums.org/showpost.php?p=10744640&postcount=202 and now everything works reasonably well.

I made a patch in order to the led works properly.

This patch contains this fix :
- in src/properties.c : I remove the led activation when the touchpad is switch off (with the keyboard and syndaemon ; or with synclient : "synclient TouchpadOff=1"). So, I don't have any more kernel panics. You can activate the led with "synclient LEDStatus=1".

- in src/synaptics.c : I modify the double tap time to 400. So, it is more easy to use the double tap to disable the touchpad. The led is automatically turn on when the double tap is activating. I also add a line to modify the option TouchpadOff as same as the double tap activation. So, the syndaemon can work and doesn't activate the touchpad when I use the keyboard.

- in tools/syndaemon.c : I modify the toggle_touchpad function. So, when you disable the keyboard with the double tap or touchpad-indicator, and after you activate the touchpad, the syndaemon continues to work when you use the keyboard.

For use this patch :

=> put it in the debian/patches directory

=> do this command in the same directory ls -1 213*.patch >> series

=> compil and install the package xserver-xorg-synaptics.

=> restart.

I will make a complete TODO after.

Thanks a lot, it works fine for me.

It's working for me, too. Thanks! I have David Härdeman's patch together with yours and all the features I need from my touchpad are working now, including right-click, click-to-drag, two-finger horizontal and vertical scrolling, and now tap the LED to disable the touchpad.

@Mohegan

I did the first part of #190 and that is the first patch that has gotten right click to work. However, now both bottom buttons do right click. Any ideas?

@Tim Dohm

Can you try the first part without the line g) (my patch?
If it doesn't work, the left and right click are described at lines 183-184 of the 209.clickpad-threshold.patch :

+ left_button_x = width * 2 / 5 + priv->minx;
+ right_button_x = width * 3 / 5 + priv->minx;

You can try to modify it.

Can you post your config ?

On my HP Envy 15 the right and the center buttons works ok. But I'm having a problem.

Initially the led is off and I can use te touchpad "normally" (I am still unable to drag and drop).
When I double tap to turn on the led, the led switch on but the touchpad stops working anymore.

Something might be wrong in the LED patch because the LEDStatus is still 0 although I have my LED switched on.

In my opinion LEDStatus should be set to 1 at the startup:

synaptics.c:
pars->led_status = xf86SetBoolOption(opts, "LEDStatus", TRUE);

Why do you think?

Sorry, I mean, What do you think?

What's happening to me is that the touchpad is working inside out. When the led is off the touchpad is enabled and when the light is on the touchpad is disabled.

In my case LEDStatus is always zero, although the LED light works correctly. When I tap to disable, the LED light turns red and the touchpad is disabled, but synclient -l and xinput list-props always show LED Status to be zero whether or not the touchpad is disabled.

@Mohegan

I tried it without your patch and right-click is still activated on both buttons. This is on an HP DV6QE. I tried editing the 209 patch but then buildpackage was returning errors.

@Airam RR

In Comment #196, If your touchpad is switched on then TouchpadOff should be zero, but your synclient -l output shows it to be 1, meaning the touchpad is Off.

It is possible to have the touchpad disabled with the LED off and vice-versa by manually changing TouchpadOff, which doesn't seem to affect the LED.

@Mohegan
Would it be worthwhile modifying the TouchpadOff logic to turn on the LED when the touchpad is off, and vice-versa?

@Mohegan
LEDStatus in my case is always zero. Regardless of whether the touchpad is on or off, or whether I turn it on or off by double-tapping the LED or setting TouchpadOff manually, LEDStatus never changes from zero. I can, however, change LEDStatus manually with synclient and that does turn the LED on and off, although without enabling/disabling the touchpad.

TouchpadOff does not change its value when i set it manually:

Damm!!! yes it change it's value ... Sorry about that!!! I'm going crazy....

So what it's wrong is the LEDStatus because:

when the LED is off -> TouchpadOff = 0 and LEDStatus = 0
when the LED is on -> TouchpadOff = 1 and LEDStatus = 0

I still think that in synaptics.c it should be added:

pars->led_status = xf86SetBoolOption(opts, "LEDStatus", TRUE);

in static void set_default_parameters(InputInfoPtr pInfo).

In that situation you'll have:

Initially the TouchpadOff variable is set to 0, that means touchpad is enabled and with the line I propose the LEDStatus set to 1.
If I doubled tap in the touchpad then TouchpadOff will be set to 1 which means that is disabled and LEDStatus set to 0.

Ok, thanks all of you !
I modify my patch.
So, just change the line g) of the first part (post #190) :

g) wget https://bugs.launchpad.net/ubuntu/+source/linux/+bug/582809/+attachment/2146855/+files/213-fix_mohegan.patch

By this new line :

g) wget https://bugs.launchpad.net/ubuntu/+source/linux/+bug/582809/+attachment/2155978/+files/213-fix_mohegan-V2.patch

This second patch contain this improvements :
=> file src/properties.c : add two lines in order to change the parameter LEDStatus as same as TouchpadOff when you use the double tap (at the end of the file) !
=> file src/synaptics.c : add the line "pars->led_status = xf86SetBoolOption(opts, "LEDStatus", FALSE);" to set LEDStatus=0 as default when start your computer
