tap-to-click and edge-scrolling broken in Jaunty

Enabling the synaptics driver's SHMConfig option, and dumping its configuration values with "synclient -l" reveals a number of differences between the intrepid and jaunty versions of the driver:

Resetting them with synclient allows the broken features to work.... briefly. It seems something is causing them to reset within a minute or so. I'm not sure if that's all part of the same bug, or a whole different problem.

On my Aver Travelmate 8100, the tap-to-click was lost, but edge scrolling works.

Also on my Acer Aspire 5633 WLMi tap-to-click doesn't work, but scrolling (both horizotal and vertical) does work.

Likely same issue as bug 320585, though one notes a loss of edge-scrolling and the other does not. The difference could be model-specific.

See also bug 320804, I've marked it is a duplicate of this one, it contains some more diagnostic attachments.

The attached patch enabled tap-to-click even when a physical left button is available.

Enable vertical scrolling even when doubletap is available.

This is a big debdiff with an updated changelog and all my patches from this bug report, from bug 320639 and from bug 320585.

While waiting for the above patches the following command works for me to enable tap-to-click:

xinput set-int-prop 7 258 8 2 3 0 0 1 0 0

Sorry, I should have mentioned:

 7 is the device number reported for the touchpad by "xinput -list" and 258 is the property called
Synaptics Tap Action by "xinput list-props 7"

Others will no doubt see different device numbers and a different set of property numbers.

Is these patches the right way to go? The main problem I have is that edge scroll no longer works (it is the only feature that I miss) and I looked at the patch. The current way is to do some auto detection of edge scroll capability. After the patch it is always enabled. Isn't more correct to correct the auto detection instead of always turning it on? I don't have any knowledge of the xserver-xorg-input-synaptics package, so I might be wrong.

Jonas: currently the vertical edge scroll is enabled only if doubletap is not detected. With my patch the edge scroll is enabled in either case.

John,

While waiting for the above patches the following command works for me to enable tap-to-click:

---------------

by typing the correct parameters it worked for me as well !! great !
Now tap-clicking is enabled !!!

But edge scrolling doesn't work !!
I've tried to put the 1 value to "edge motion always" without result !!

xinput set-int-prop 7 258 8 2 3 0 0 1 0 0 worked for me too.

I've realised that although I no longer have edge scrolling I do have 2 finger scrolling working which I've never had before.

I guess to get the edge scrolling back I need to disable the 2 finger scrolling first.

@Romain1101,

Doing xinput list-props 7 (substituting for your device number) do you have the first number
of "Synaptics Edge Scrolling" as a 1? This is what I believe is being set to True by Alberto's patch. I'll bet that's what you need. Perhaps the double click detection is something you have and I don't because this is already a 1 for me.

My edge motion always is 0 and my vertical scrolling works. I do not have a special area of the touchpad for scrolling as I read about in some of the documentation, it is simply the right side of the normal touchpad I use.

If the x value for the edge is higherfor you than before and you have a smaller touchpad than I do perhaps that could explain our different results. You might try lowering the second value of "Synaptics Edges", though my value for this is 1532, rather than the 6051 reported above by Max.

I try to figure out what the various xinput properties are by comparing the xinput properties list to the output of "man synaptics", the xorg.conf parameters.

Just some ideas. I hope one helps.

@Alberto:

Thanks for the fast patches. Wow!

Do you think that palm detection ought to be turned on by default as before or should Ubuntu follow upstream?

In my case doubletap don't work. Checked the code in the old version and
can see that the scroll is always enabled as well, so assume no issue
doing it in the new version as well.

Just updated to a new version (0.99.3-1ubuntu2) and that solved my issues. I updated from main mirror, so it might not be available at the mirrors yet. Please try to update to new version when it hit the mirrors.

Thanks for fast resolution :-)

@John ,

Well as i said before :

Putting the right value - in my case - xinput set-int-prop 4 Synaptics Tap Action(303) 8 2 3 0 0 1 0 0
enables the tap-to-click.

Then I succeeded by typing "xinput set-int-prop 4 Synaptics Edge Scrolling (291) 8 1 1 1
to enable my edge scrolling.

But these changes come back to their initial value as soon as I reboot my pc.
What can I do to fix this ?

Then I went and saw that line in synaptics.c
who put the value at TRUE if double-tap isn't detected...
so i changed it to "TRUE" directly as does the patch that has been provided here...

my question is...then what ?? What I have to do to compile this so as to install it with apt-get ?

If it may help, i provide my xinput output.

Actually I don't know what is the "2 fingers scrolling" ?
Could u tell me what it consist to perform on my touchpad ?

I think the easiest thing for you is to wait some hours and wait for
version 0.99.3-1ubuntu2 shows up on the mirrors. Looks like the patch is
included in that version. Scroll is working for me again.

/Jonas

OK, so -1ubuntu2 has fixed tap-to-click for me, but....

When I first logged in, edge-scrolling was working. About 2 minutes later, it had ceased to work!??

/me rolls back to the Intrepid package again for now...

@Romain1101:
I expect that we will see the launchpad janitor add some messages here about a fix being released (I don't know for sure) and if so it will automatically change the status. Some time after that (minutes or hours, not days) you should see the updates are available icon in your panel and then you can just allow those updates as you usually do. If you look at the packages first you should see xserver-xorg-input-synaptics 0.99.3-1uuntu2 and those will be Alberto's patches.

You won't have to use apt-get, but once you see them in the update manager you can close the update manager and use apt-get if you want. If not it will all be automatic.

My guess is that those who have tested the new package already have downloaded it from packages.ubuntu.com and installed the downloaded .deb with a lower level program. I'm going to wait myself.

@John:

Well I was able yesterday evening to upate the package.
Everything works fine!

Nothing to say except that the pointer is now such stable that I'm regreting the motion of my pointer
yesterday which was casi unstable and was able to move very quickly !
Such a way that keeping only my finger on the pad without motion and the pointer beginned to shake !!

No pasa nada !!

Where I can read that the new package features the patch from yesterday ???
I mean yesterday we were really talking with someone who put the new-good pkg online ?

Bye

One last thing....

Sometimes u wrote "rolls back to previous version -intrepid or sth else..."
Thats the very thing I would appreciate to learn, yeah maybe u're smiling but thats true,
with that easy adept put in jaunty....I don't know how to get back a previous version from a pkg ??

Someone to teach me this ???

Is it too slow? Too sensitive? Please explain the problem more in detail.

@Alberto...

About my pointer,
"sensitive" That's the word I missed in my previous mail -> My pointer isn't sensitive enough for me !!
I don't know exactly to describe, just that yesterday it was a bit crazier !!! and I liked that...
today it's like I have to push harder, with a low accelFactor - that I've set upper !
So I'm reading the patches added to the package and I read the ultimate

"* 107_reduce_cursor_speed.patch:
 - Reduce the cursor speed. (LP: #320639)"

I'm gonna read what it changed, maybe that the point !!!

@Alberto,

Ok I set back the value of MaxSpeed and MinSpeed as they were yesterday...It went back to that behaviour I was talking about !!
nice !! I changed it with synclient, I will see if it comes back rebooting the PC.

Anyway, nice to have some people like you, I learned a lot !!
I didn't know that I could middle/right-click with multiple fingers with my touchpad !!!

I just miss the ultimate info -> how to roll back to a previous version when a new package doesn't come good !!

Thanks 4 everything!

0.99.3-1ubuntu2 fixes tap-to-click and edge scrolling on my Acer, but left button click doesn't work reliably anymore. Very often I have to click twice, and I suspect that it's because behind the scenes it clicks too often. Single left click also can produce left+right and paste current clipboard contents accidentally.

Confirming Sergey's issues. I've got them as well.

That patch does not fix my alps TP. I have to add RightEdge=800
And another thing I noticed is that the tap has a lag of 0.5~1 second. Is this tapping problem also valid to you?
Thanks

0.99.3-2ubuntu1 improves the situation: clicking left button almost never produces a left+right click for me, edge scrolling and double finger scrolling (which I've never used before) work, as does tap-to-click. Left click is still jittery (sometimes it still does left+right; left click and drag always produces left+right instead), but it's much better. I'm attaching the output of xinput. Thank you!

Well,

I went back to the previous version, this one removed the edge scrolling for me !!

Using 0.99.3-2ubuntu1 on an Acer Aspire One, something truly bizarre is happening.

Immediately after login, edge-scroll works. Shortly after login, edge-scroll stops working. When this happens, 'xinput list-props' and 'synclient -l' *DISAGREE* about the position of the right edge of the touchpad!? - see here:

maxb@aao:~$ synclient -l | head -5
Parameter settings:
    LeftEdge = 1632
    RightEdge = 6143
    TopEdge = 1575
    BottomEdge = 4281
maxb@aao:~$ xinput list-props 5 | head -3
Device 'SynPS/2 Synaptics TouchPad':
 Device Enabled (109): 1
 Synaptics Edges (255): 1632, 5312, 1575, 4281

Using 'synclient' to reset the RightEdge value to what 'xinput list-props' shows throughout *re-enables* edge scrolling.... for a while. After a minute or so, edge scrolling breaks again, and inspecting the RightEdge value with 'synclient -l' shows that it has mysteriously reverted to the broken value, apparently spontaneously !?

I will attach the full 'xinput list-props' output for both 0.15.2 and 0.99.3, though I have summarized the interesting bit above, AFAICS.

I'm also affected by this bug. Edge scrolling worked fine with 0.15-series synaptics driver but broke after upgrading to the 0.99 series. Input properties for my (alps) touchpad attached.

And I should clarify that the above attachment is with the 0.99 series driver, where edge scrolling does not work.

Can you please advise which version of 0.99 series you have installed.
Here I use below version and edge scrolling is working.

onas@miraculix:~$ dpkg -s xserver-xorg-input-synaptics | grep Version
Version: 0.99.3-2ubuntu1

seanzer@blayze:~$ dpkg -s xserver-xorg-input-synaptics | grep Version
Version: 0.99.3-2ubuntu1

Scroll does not work for me, it broke after I updated to Jaunty. Tap to click works, two finger scrolling does not work. Although I have an XPS notebook with an ALPS touchpad, scroll used to work fine before update. I've always been using the synaptic driver.

Also, my edges line up, and I can use the gsynaptics to enable/disable the touchpad and tap clicking and change the speeds, but no matter how I modify the horiz/vert scroll or even circle scrolling, none work.

When I exec xinput list-props, it shows that the scroll functions are set to 0.

seanzer@blayze:~$ xinput list-props 3
Device 'AlpsPS/2 ALPS GlidePoint':
 Device Enabled (93): 1
 Synaptics Edges (224): 40, 983, 42, 725

 Synaptics Scrolling Distance (232): 25, 25
 Synaptics Edge Scrolling (233): 0, 0, 0
 Synaptics Two-Finger Scrolling (234): 0, 0 ...........

Correction, I was able to enable (LOL) two finger scroll, edge scroll and circle scroll still do not work.

Edge Scrolling doesn't work here either.
Driver version 0.99.3-2ubuntu1

The attached debdiff should fix the problem with drag and drop and fix the speed problem.

I'll see what I can do for ALPS touchpads.

Information for ALPS tps:

I saw that you lowered the speeds MinSpeed=0.2 MaxSeed=0.5
ALPS users will need MinSpeed=0.45 MaxSpeed=0.75 and AccelFactor=0.02
for the tp to be usable

we also need for a tap not lagged
SingleTapTimeout = 0
ClickTime = 0

for scrolling we need
RightEdge=830

if these settings cannot be applied in the .c file, it could be
possible to add them in hal, only if the touchpad is ALPS

Setting RightEdge to 800 fixes Vertical Scrolling on my 'AlpsPS/2 ALPS GlidePoint' (Dell Vostro 1400) with xserver-xorg-input-synaptics 0.99.3-2ubuntu1.

I have tried the new patch, and it does fix the left-click-causes-middle-click problem. However, the touchpad is still too sensitive. This is especially true for small movements, and it makes it quite hard to click on small links and buttons.

This bug was fixed in the package xfree86-driver-synaptics - 0.99.3-2ubuntu2

Please open a new bug about the sensitivity issues.

Thanks,

Reopening, edge-scrolling still broken in -2ubuntu2 same as in my comment 42.

moving the milestone; edge scrolling is a lower-impact issue, and it also now Works For Me.

I am running Jaunty on a Acer Aspire 5051AWXMi and have not issues with the synaptics driver. Edge-scrolling, tab on click works. Also the sensitivity is fine with me. Jaunty has latest updates from today.

Works for me - both sensitivity and tap-to-click are functioning properly.

Reopening, edge-scrolling is still broken on the Acer Aspire One.

Do you have an ALPS touchpad like me?

Is this the same bug ?

Click and Tap work fine, just the edge srolling no longer does...

Edge scrolling not working here on lenovo thinkpad r61.

0.99.3-2ubuntu2 fixed all touchpad issues for me. I have a "SynPS/2 Synaptics TouchPad" though, not ALPS.

The Acer Aspire One also identifies its touchpad as a "SynPS/2 Synaptics TouchPad", but edge-scrolling doesn't work there.

I've got a compal FL91, and edge scrolling is not working. 2-finger scrolling and tap to click work fine.

Edge scrolling stopped working for me to (SynPS/2) but two-finger scroll was
enabled instead, try scrollling with two fingers (os x-style) if edge scrolling
was disabled

I have an "AlpsPS/2 ALPS GlidePoint", and neither edge scrolling or tap to click are working for me on Jaunty with latest updates. Also in the "System -> Preferences -> Mouse" application there is no tab for "Touchpad" to turn tap to click on and off anymore.

I think edge-scrolling not working is due to design change. This is from driver release notes:
http://lwn.net/Articles/317613/

"Note: Due to the ubiquity of multi-touch capable touchpads, the driver will
pick two-finger scrolling over edge scrolling if two-finger detection is
supported by the hardware. Edge-scrolling is then disabled.

Kernels up to excluding 2.6.29 announce multi-touch capabilities for all
synaptics touchpads even if the hardware does not support it. If you have a
such a touchpad, you will need to enable edge scrolling explicitly in the
configuration."

Note sure if Jaunty will stay with 2.6.28 or move to never kernel, but this might be big issue for people upgrading...

My touchpad (Toshiba tecra A9) isn't multi-touch capable.

How do I enable edge scrolling in jaunty so I can test if it's realy related to that problem ?

I guess I'm lucky but here everything works:
* Tap-to-click (and double-tap to double-click);
* Left button and left-button drag-n-drop;
* Right edge scrolling;
* Two-finger vertical scrolling;
* Four-way middle button works for vertical scrolling.

Neither edge scroll nor two finger scroll work for me. I'm not sure but I think that my touchpad does not support multi-touch. Edge scroll worked with older versions of synaptics driver in Jaunty and I still like to have an opportunity to use it.

Hope this problem will get enough attention.

I just did a clean install of Alpha4.

- The touchpad xfree driver is not installed, so tap-to-click did not work
- After installing the driver, everything work, with exception of edge scrolling

On Acer Aspire One, xserver-xorg-input-synaptics 0.99.3-2ubuntu2:

Horizontal scrolling, tap, tap-and-drag all work. Vertical scrolling works for a few seconds and then stops working until next reboot.

On my Dell Vostro 1500, tapping, edge scrolling, and two-finger scrolling all work fine. (I have tapping disabled, though.)

> I think edge-scrolling not working is due to design change. This is from driver release notes:
http://lwn.net/Articles/317613/

No, we reverted that change with the 106_always_enable_vert_edge_scroll.patch patch.

[No need for this to be open against both source and binary packages]

@Max Bowsher:
The case on Acer Aspire One is idiosyncratic. You may try whether this works for you or not:
# synclient FingerLow=9 FingerHigh=12

I'm testing the latest Synaptics on Acer Aspire One and I've noticed that the device reported wrong range for pressure. The device reports that the available finger pressure range is 0 - 255, while testing with "synclient -m 10" shows that the maximum pressure is only 70. So you've to press *really hard* along the right edges to scroll. The command above set a sane value for this device.

If that works for you, we can workaround this quirk by setting it by using hal.

# synclient FingerLow=9 FingerHigh=12

This works for me on AAO.

Can anyone who has an ALPS touchpad test the package in my PPA, please?

Hi Alberto,

I have installed your package. I actually found on doing so that no previous
version of that package was installed on my Jaunty system (a Sony Vaio
VGN-SZ71WN). I'm not sure if it should have been there and wasn't added when
I installed Jaunty (the 2/2/09 nightly I believe).

After installing your package and logging out and into gnome again, I find
that the mouse preferences screen now has a third tab "touchpad" again, and
tap to click is working.

Vertical scrolling is also working but only to a small degree. It does not
work every time. I'm finding it hard to get it to work now actually.
Pressing very hard does not seem to help the situation.

darylb,

Yes, there was a bug in Jaunty up until the beginning of February that would prevent the xserver-xorg-input-synaptics package from being installed by default on new installs.

It would be good if everyone tracking this bug could verify that they have the package installed, and if they've commented on this bug previously, to report bug whether their touchpad is still misbehaving with xserver-xorg-input-synaptics installed.

darylb: can you attach the output of the following command?
xinput list-props 7

replace 7 with the identifier of your synaptic device.

Alberto,

Here is the output for the alps device on a Sony Vaio VGN-SZ71WN:

That's great! can we edit those values runtime, without having
SHMConfig enabled?

Ok, my bad. Can you test the latest package in my PPA (0.99.3-2ubuntu3.1 ), please?
https://launchpad.net/~albertomilone/+archive/ppa

Alberto,

That works now! I tested vertical and horizontal scrolling and both work.
The active area on the right of the touchpad for vertical scrolling though
is about 1.5 times as wide as it needs to be for a finger. I can leave a
good gap on the right of my finger and still scroll. This is not how it was
in Intrepid.

Thanks,
Daryl

darylb: can you attach the output of the following command again, please?
xinput list-props 7

replace 7 with the identifier of your synaptic device.

Alberto,

The package in your PPA has also fixed edge scrolling on my Dell XPS m1530 which has not worked in some time.

It only fixes the scrolling problem. the tap lag is still present. Is
this a wanted behaviour?

dashua: thanks for reporting.

Nicolò: no, it's not but I don't own an ALPS touchpad therefore I rely on your feedback. I'll upload a new version with the following settings:
SingleTapTimeout = 0
ClickTime = 0

But of course I'll have to hear from others to make sure that these values don't cause problems to other ALPS touchpads

Alberto, here is my output now. The device number seems to have changed to
8, I'm not sure if that is relevant or not.
Now that it is mentioned I do notice a lag between tapping the touchpad and
the click registering, I didn't notice it before. It seems to be about a
half-second lag.

Ok, I've just uploaded 0.99.3-2ubuntu3.5 to my PPA. Here's a list of changes (which will only affect ALPS touchpads):
 - Set RightEdge to 840 (hoping that it solves darylb's problem).
 - Set ClickTime to 0.
 - Set SingleTapTimeout to 0.
 - Set MinSpeed to 0.45.
 - Set MaxSpeed to 0.75.

Let me know if the new settings work better for you or if something doesn't work. In the latter case, please attach the output of of the following command:
xinput list-props 7

replace 7 with the identifier of your synaptic device.

Hi Alberto, I have tried the new version. It fixes the tap delay for me. However the right edge for vertical scrolling is still much too wide. On my Vaio, vertical scrolling works all the way from the right edge to the middle of the right hand button under the pad. Here is a picture of the laptop to show what I mean: http://www.notebookcheck.info/uploads/pics/sz71W-2_09.jpg. I've attached the output of the command you requested.

In my laptop I have set a value of 830 and it's ok for the scrolling
area. It's a dell latitude E6400.

darylb: how about cursor speed? Do you prefer those new values, like me?

I'd really want to know if those xinput values can be runtime
modified,or if a restart is needed.

At the advice of https://bugs.launchpad.net/ubuntu/+source/xfree86-driver-synaptics/+bug/320632/comments/86, I ran the following:
sudo apt-get install xserver-xorg-input-synaptics
and logged out and back in. Both tap-to-click and edge-scrolling now work fine.

Thanks Steve!

One tiny annoyance: my mouse speed seems to have returned to default after installing the above.

Nicolo: How do you change the value? Perhaps I can play with it and come up
with a number that works better on my laptop.
Regarding the cursor speed I have been playing around with the speed
settings in the mouse control panel so I'm not sure I can objectively
compare them (I'm not sure how to set it back to default). I thought it was
too slow before though so if this update has made it slightly faster then I
would agree its an improvement.

Alberto,

I just updated to package xserver-xorg-input-synaptics_0.99.3-2ubuntu3.5_amd64 and all is still working.

xinput list-props attached.

dashua

With the values I suggested to Alberto the cursors speed is higher.

Anyway I've cometo those values playing around using synclient. To
enable synclient you have to follow this howto:
tps://help.ubuntu.com/community/SynapticsTouchpad#shmconfig

Then you can use synclient to edit the options.when you've found
something acceptable for you, roll back the change and past here your
values, so I can test them too

darylb: can you attach your /var/log/Xorg.0.log ?

I have attached my log file. I also noticed this in it which may be of interest:

AlpsPS/2 ALPS GlidePoint: x-axis range 0 - 1023

Nicolo: Thanks I will play with that later on this evening when I have more time, but I suspect this may be related to the fact my touchpad has width 1024 and 850 is set at the threshold for the right scrolling margin. What width does yours report?

I get this in xorg.0.log:

x-axis 0-1023
y-asis 0-767

I've tested the new package. The speed and the tap lag are resolved now!

Also for me the scrolling area is too big with this package... I've
played around with values and I see that 895 is ok.

Please test it darylb:
synclient RightEdge=895
(after having followed the SHMConfig howto in the site)

Alberto do you know how to change the RightEdge and other properties
without synclient and SHMConfig?

Sure, if darylb reports that 895 works for him and this doesn't cause problems to other ALPS users I'll put it in my patch.

RightEdge=895 doesn't cause any problems for me. I'd actually go so far as
910 though. With 910 my finger needs to be almost touching the right edge
(but not quite touching the edge) for it to work. With 895 the gap to the
edge can be even larger. In my opinion your finger should touch or almost
touch the edge for scrolling to work. However if it is likely to cause
problems with other touchpads, 895 is definately an improvement over the
previous settings. <https://bugs.launchpad.net/bugs/320632>

910 is also ok for me, I don't mind the fact that I need to touch the
border to scroll

I also have an alps touchpad and the 0.99.3-2ubuntu3.5 package from the ppa works fine in every way for me.

Please try if a RightEdge of 910 is ok for you too

Ok, I've just uploaded 0.99.3-2ubuntu3.6 to my PPA. Here's the only change (only for ALPS touchpads):
 - Set RightEdge to 910.

Let me know if the new settings work better for you or if something doesn't work. In the latter case, please attach the output of of the following command:
xinput list-props 7

replace 7 with the identifier of your synaptic device.

If there are no problems with the new package, I'll prepare a debdiff to make sure that my changes are ready for the upload to Ubuntu's repository.

Well, maybe 910 is too high.. I'd go with 900.
I say this because it happens that when I scroll, my finger does not
move perfectly vertically, but can move a bit to the left, so in my
opinion just a bit more of scrolling area is better

it's set to 900 in 0.99.3-2ubuntu3.7. Feedback is welcome

Just upgraded to 0.99.3-2ubuntu3.7.

With 900 it works fine. (900 was too small)

Thanks

Of course I mean 910 is too high.

900 works fine for me too.

i has the same problem then i build synaptics-1.0 from source.
I solve it by creating file /etc/hal/fdi/policy/synaptics.fdi
and put following lines in it:

<?xml version="1.0" encoding="ISO-8859-1"?>
<deviceinfo version="0.2">
<device>
<match key="input.x11_driver" string="synaptics">
<merge key="input.x11_options.CircularScrolling" type="string">true</merge>
<merge key="input.x11_options.SHMConfig" type="string">true</merge>
<merge key="input.x11_options.VertTwoFingerScroll" type="string">true</merge>
<merge key="input.x11_options.TapButton1" type="string">1</merge>
<merge key="input.x11_options.TapButton2" type="string">2</merge>
<merge key="input.x11_options.TapButton3" type="string">3</merge>
<!--
<merge key="input.x11_options.VertScrollDelta" type="string">100</merge>
<merge key="input.x11_options.LeftEdge" type="string">1700</merge>
<merge key="input.x11_options.RightEdge" type="string">5300</merge>
<merge key="input.x11_options.TopEdge" type="string">1700</merge>
-->
</match>
</device>
</deviceinfo>

So no need to put anything else in startup scripts and all feautures will work after futures updates.

Alberto,

Perfect.

Thx.

I didn't test your package because now I don't have my laptop here,
but I think it's ok!

Alberto, 0.99.3-2ubuntu3.7 works fine for me too, thanks for the fix!

But I've noticed one weird thing: when I click on the gnome workspace switcher in the panel, the workspace switches as it should. But the mouse pointer also jumps about 100 pixels to the right. Which it didn't do with earlier versions of the synaptics driver (i.e., not from the PPA).

Hmm, that is strange. Are you using KDE or gnome?
I just tried it here on gnome and that doesn't happen to me, no matter where
I put the workspace switcher applet.

I'm using gnome. But I noticed that it only happens with the compiz "Desktop cube" plugin and not with "Desktop wall". So it might be a compiz bug.

0.99.3-2ubuntu3.7 from the ppa also fixes the problem with a too high RightEdge value on a Toshiba Tecra S1.

I encounter no problems with this version anymore.

 Not working on a Dell Vostro 1500 for edge scrolling until i add this to hal fdi:

<merge key="input.x11_options.HorizEdgeScroll" type="string">1</merge>
<merge key="input.x11_options.VertEdgeScroll" type="string">1</merge>

Bellegarde: those values are already enabled in the driver.

1) What version of Ubuntu are you using?
2) can you attach the output of the following command?
xinput list

Thanks alberto, upload sponsored.

Hardware: ALPS GlidePoint.

Alberto Milone's PPA package solved the bug where edge scrolling did not work. It now works just fine. Thanks.

Reopening again, edge scrolling still broken on Aspire One, as described in https://bugs.launchpad.net/ubuntu/+source/xfree86-driver-synaptics/+bug/320632/comments/42.

It's not a pressure issue as some have suggested since - in that comment I specifically note that RightEdge is misbehaving in mysterious ways.

Max Bowsher: can you try commenting out the whole "InputDevice" section about your touchpad from your xorg.conf (and its entry in the "ServerLayout" section, if you have one) and restarting X, please?

My xorg.conf has no "InputDevice" sections - only the ultra-minimal "Device", "Monitor" and "Screen" sections that are the jaunty default, and a "ServerFlags" setting "DontZap" "false".

Max,

You didn't mention if you actually tried the FingerLow/FingerHigh thing. I had exactly the same problem, same symptoms, on exactly the same hardware. I didn't think the fix would work but I tried it anyway, and it did work.

Alistair:

I didn't, there really didn't seem to be any point when I had already determined that the problem was the RightEdge setting spuriously resetting itself to a too-large value.

For the sake of completeness, I tried the Finger{Low,High} setting: it didn't fix the bug. It did allow some edgescrolling, but it was necessary to awkwardly stroke only the extreme edge of the touchpad. Meanwhile, the changed settings made the touchpad awkwardly oversensitive for ordinary pointer movement.

The Finger{Low,High} settings should be left at their current defaults - what needs to be done is to find and fix whatever keeps spuriously resetting the RightEdge value.

I've just done some testing, and I've narrowed down the exact behaviour I observe:

I set a loop of "while sleep 1; do synclient -l | fgrep RightEdge; done" running to monitor the RightEdge value.

Immediately after bootup, the value is 5132. Scrolling *works*! If I very diligently avoid touching the extreme right edge of the touchpad, scrolling continues to work. The moment I touch the extreme right edge of the touchpad, the value printed from the monitor loop changes to 6142. Scrolling now doesn't work, no matter how carefully I touch only the extreme right edge when trying to scroll. I run "synclient RightEdge=5132" - scrolling works again! I touch the right edge - RightEdge reverts to 6142, scrolling no longer works.

Weird.

I hope this means something to someone more familiar with the driver source.

I just wanted to comment that I am still experiencing the same bug as Max Bowsher, with the same results using the synclient RightEdge=5132 command.

I am experiencing this on a Dell Mini 9. I did further testing booting from an Intrepid USB drive and didn't have the loss of Scrolling issue.

If there is any additional information I can provide, or anything I can test, please let me know.

Thanks,
Adam

I have now git bisected. In retrospect that was unnecessary, if only I'd read the commit messages more carefully. The culprit is:

commit 3db3f4e04c7038477a03b092c55dfd063224f034

    Auto-adjust right_edge for touchpads with hardware scroll area.

    If RightEdge is specified as a config option, ignore the SpecialScrollArea.
    Otherwise, adjust right_edge to the bounds of the hardware scroll area.

which is "auto-adjusting" my right edge off the edge of my touchpad

I found that the fingerlow/high fix moved the scroll area right as well, but for me it was an improvement. Previously the scroll area was so far from the right edge of the pad, that it didn't actually reach all the way to the edge.

Judging by some careful experimentation with synclient -m, it's not that it moves the region, it's that if you're only touching the very edge of the pad, it's impossible to get more that about 25 pressure units.

A question to Alberto: I missed why you still haven't pushed the
update into jaunty

Thanks for narrowing it down to that change. I think just reverting that patch is probably the wrong thing to do, since that would regress the feature entirely. Instead, further analysis is needed in order to discern why with this patch it is failing in this fashion. My guess is that it is incorrectly making automatic adjustment assumptions with this hardware.

Also, I'm beginning to suspect this may have a hardware-specific aspect to it, in which case I'm unsure that blocking the release on this is warranted. But I'll leave the milestone/target alone for now; I think a fix is within sight.

Alberto, do you have further comments/plans on this that need accounted for?

I haven't had the time to look at this very hardware specific bug but I think I can try to revert patch only for ALPS touchpads so as not to cause regressions with synaptics touchpads.

Is it possible to ship a hal .fdi file in the package so that ALPS
touchpads will work?

The attached debdiff should solve the problem. The change is minimal and is just an addition to my previous patch so that if an ALPS touchpad is detected the right edge is not auto adjusted.

Alberto:

maxb@aao:~$ lshal | fgrep -i alps
maxb@aao:~$ lshal | fgrep -i synap
  info.product = 'SynPS/2 Synaptics TouchPad' (string)
  input.product = 'SynPS/2 Synaptics TouchPad' (string)
  input.x11_driver = 'synaptics' (string)
maxb@aao:~$

It appears the Aspire One's touchpad is not an ALPS device?

Ok, I'll work on another patch but we'll have to test the package for regressions as it will affect all synaptics touchpads.

The attached debdiff sets the SpecialScrollArea to False by default.

I have uploaded the package to my PPA, can you try it and let me know how it goes, please?

Hi Alberto,

This package fixed the edge-scrolling disappearing after a few minutes. Thanks !

Hi!

My Synaptic touchpad worked fine and still does with the package from the PPA.

HTH.

Works for me on Acer Aspire One A110 (was broken before).

The package from PPA has fixed edge scrolling on my Asus EeePC 701 with Synaptics touchpad (was broken before).

Hi Alberto,

The package from the PPA has fixed edge scrolling for me on my Asus N50Vn with Synaptic touchpad.

Thanks!

Works on my Dell Mini 9 as well. Don't know if anyone has told you you're
awesome today, but you are and thanks Alberto.

Tapping and scrolling stopped working on my SynPS/2 Synaptics TouchPad after version xserver-xorg-input-synaptics_0.99.3-2ubuntu3_amd64.deb. So 0.99.3-2ubuntu4 is the first version it ceased to work.
The bug is still present in 1.1.0-0ubuntu1.

Serbitar: can you attach the output of this command, please?
xinput list-props name_of_your_synaptic_device

replace "name_of_your_synaptic_device" with the name of your synaptic device (as reported by "xinput list")

Ive attached the output with the working package 0.99.3-2ubuntu3 and the non-working one 1.1.0-0ubuntu1

Serbitar: 1.1.0-0ubuntu1 is not available in Ubuntu Jaunty. Can you please install version 0.99.3-2ubuntu4, restart the xserver and attach the output of the same command?

Serbitar appears to be using the package from my PPA. Sorry about that.

True. 0.99.3-2ubuntu4 wroks. I thought I had it installed when the bug occured the first time. My fault. Thanks for the time.

Serbitar, Michael: thanks for making it clear that the problem affects the package in the PPA and not the package in Ubuntu.

I think this bug is finally fixed.

The package doesn't appear to be available in the location listed below. How do I obtain it?

Thanks.

I installed Ubuntu 9.04 NBR Beta last night and I have the edge scrolling issue described above on my Asus Eee PC 701, i.e. it initially works ok then stops working after a few minutes. Wouldn't the latest version of this package be installed during installation of the OS? I will check which version I have tonight.

Confirmed update to latest version in repository fixes edge scroll
problem on Asus Eee PC 701. Thanks

Is anything special needed to (rei-)enable two-finger scrolling, etc? I used to have two-finger scrolling on Jaunty, but it is gone now. I have edge scrolling and tap-to-click. And, as others noted, if I install Mike Marley's newer driver, I lose even that.

To be sure of which version I am running, after forcing a delete of Mike's driver, reinstalling and rebooting:
