scrollwheel emulation breaks after suspend with 2.6.27-7

Despite this report holding true across multiple test suspend cycles over the weekend, opening my laptop this morning and setting the xinput properties has left me with working scroll.
Bit of a head scratcher, frankly.

After further suspend cycles it seems that it doesn't work more often than it does work, to the extent that the previous comment seems to have been an isolated incident

i am also experiencing the same issue on a thinkpad x60s. scrollwheel emulation works fine after reboot and breaks after suspend. unlike chris, it never came back after suspend.

gerd

latest update a few minutes ago didn't solve the problem either.

i am now on 2.6.27-7-generic

gerd

Is it possible that the device name is differs on different machines? I've a new Lenovo X301 and I don't even have the "TPPS/2 IBM TrackPoint" device. The only device that looks similar is the "DualPoint Stick", but executing the xinput with this name doesn't event make the scrolling work before a suspend.

The device name does change, but actually based on the BIOS setup. It's called TPPS/2 IBM Trackpoint on mine because I disable the touchpad in the BIOS.

Reboot and do "xinput list" to find the device, then "xinput list-props" to get the properties of that device.
(You need to reboot because if you set properties that don't exist, they are created and ignored by the driver, so rebooting gets you a clean slate).

I just came back from a hibernate and the trackpoint stopped working on my x60t as well:

/etc/acpi/resume.d $ xinput list-props 6
Device 'TPPS/2 IBM TrackPoint':
        Device Enabled: 1
        Middle Button Emulation: 1
        Middle Button Timeout: 50
        Wheel Emulation Inertia: 10
        Wheel Emulation: 1
        Wheel Emulation X Axis: 6, 7
        Wheel Emulation Y Axis: 4, 5
        Wheel Emulation Timeout: 200
        Wheel Emulation Button: 2
        Drag Lock Buttons: 0

I am also using 2.6.27-7-generic.

And by trackpoint in my above comment, I was just referring to the scrolling.

maybe this should be visible as intrepid bug?

I don't seem to see this problem anymore as of yesterday's updates.

Hmm, never mind. It still seems to happen. I must have inadvertently restarted X last time.

I'm also experiencing this problem: scroll emulation set with xinput works initially, but stops working after a suspend/resume. Same versions as above.

I'll add that it also stops working after a mere VT switch (which may be the real cause, since suspend/resume seems to do a VT switch implicitly).

Trying to turn it back on with xinput seems to partly work: button 2 presses stop being emitted and the cursor freezes while button 2 is down, but no button 4/5 events are emitted. (And, occasionally, re-running xinput WILL work after suspend/resume.)

I can verify the same mis-behavior on a Lenovo T61. I've defined a mouse-wheel.fdi for HAL, and on boot, all works as expected. However, after resuming from suspend or hibernate, scroll functionality no longer works.

I have the same problem, however, I can switch to another user and there scroll-wheel emulation works.

I have this problem as well (Thinkpad X61 Tablet). It works when you switch to another user because that starts a new instance of X.
This applies to pretty much all Thinkpads, and they are quite popular among Linux users, so it would be nice if this could be fixed prior to the release.

The problem appears to have been fixed upstream. I installed the latest copy from the git repository, and have tried suspending and resuming over a dozen times and it's still working.

So I tried various upstream versions back and forth. The bug was supposed to have been fixed in the b0737bdbd1f6e601eb4984b6f4cb49279190984c commit, however that commit appeared to introduce another bug. I tried the commit before that, 5f2c8a2dcdf98b39997ee5e7c9a9ace3b640bfa3, and for some reason that one works perfectly, so far at least. I had some problems with HEAD, which included X crashing when Ctrl-C was pressed.
So I haven't been able to pinpoint exactly where this problem was fixed, and as such can't post a diff for that. I will continue investigating the problem when I have the time.

Anyone who wants to fix the problem now can follow these instructions:
sudo apt-get install build-essential git-core
sudo apt-get source xserver-xorg-input-evdev # You can delete the stuff it downloads to your working directory, this is only to get all the build dependencies
git clone git://git.freedesktop.org/git/xorg/driver/xf86-input-evdev
cd xf86-input-evdev
git reset --hard 5f2c8a2dcdf98b39997ee5e7c9a9ace3b640bfa3
./autogen --prefix=/usr
make
sudo make install

Now restart X and it should work properly. (at least it did for me)
If it doesn't work, first try rebooting, and if it still doesn't work, reinstall the Ubuntu version with
sudo apt-get -s install --reinstall xserver-xorg-input-evdev

Unfortunately I don't know how to make a deb out of this.

Oops that should be sudo apt-get install --reinstall xserver-xorg-input-evdev for reinstalling the ubuntu version.

5f2c8a2dcdf98b39997ee5e7c9a9ace3b640bfa3 seems to be working well for me so far. Thanks Niklas.

(NB: I did have to manually install a couple extra xorg related -dev packages to compile it.)

Hm yeah I suppose the apt-get source should be apt-get build-dep xserver-xorg-input-evdev, sorry about that.

Niklas: Is that the only patch required to the current Intrepid version, or is that a diff against current git?
(If the former I hope we can get this pushed through as an SRU, if the latter then it'd have to be a backport at best, I think)

Chris: Those are the commits that fix this problem, nothing else, so it's not a new version or anything.

Oh and the commits are b0737bdbd1f6e601eb4984b6f4cb49279190984c and af096e8c5d8b425f725a37bf4a98e205e70716e9

I'm a little confused, those patches don't seem to apply cleanly to the package in intrepid?

Weird, it worked for me and I've been using it for a week now, but when I tried it on another computer it didn't apply.
I patched it manually and made a diff, so here it is. See if this works for you.
This is diffed against xserver-xorg-input-evdev_2.0.99+git20080912-0ubuntu5 and contains the code of both of the above diffs. I patched with patch -p1 < preinit.diff, configured, compiled and installed flawlessly.

I did not apply the patches, but I would like to comment that it happens to me every other time I go into suspend... (For example, I turn on the laptop and middlemouse scroll works, then I suspend and resume and it does not, then after another suspend/resume it does work again.)

I am using intrepid ubuntu x86_64 and a thinkpad x61t

Would someone who understands all of this please post a NEW summary of instructions on how to fix this? I have read through it but I am not sure what exactly I need to do to fix this problem.

I applied Niklas Vanhainen's patch to xserver-xorg-input-evdev_2.0.99+git20080912-0ubuntu5
but it doesn't fix the problem.
Now scrollwheel emulation works only in Up direction before and after suspend/hibernate.

With current xserver and kernels (as of 3 Nov 2008), I'm no longer experiencing this issue on a lenovo T61; everything works as expected.

can you please post the exact versions you use? for me, with current updates as of today, it still doesn't work. i have a thinkpad x60s.

the problem still shows as when it started: scrollwheel emulation works after reboot or restart of X and stops working after VT switching or suspend/hibernate.

i also tried applying those mentioned patches now. but it fails when trying to get the source for xserver-xorg-input-evdev?!

when searching for the xserver-x...

restarting of X seems to leviate the problem and restores scrollwheel emulation - but it is a bit against the thought of suspending/hibernating as you loose your current session and open programs.

and by restarting X i mean you can either kill it with crtl-alt-backspace or just log out and then in again.

Niklas: thanks for re-rolling the patch, that one applied fine and I'm testing it now. It's already survived one suspend/resume cycle. I'll report back later as to how it's going.

Ok, just to make this clear for those attempting to apply this patch,
follow these instructions, the instructions I gave above was for
getting a version from git where this problem doesn't exist.

sudo apt-get build-dep xserver-xorg-input-evdev
apt-get source xserver-xorg-input-evdev
cd xserver-xorg-input-evdev-2.0.99+git20080912
patch -p1 < /path/to/preinit.diff
./autogen --prefix=/usr
make
sudo make install

Restart the X server.

Post results here along with the problem you were experiencing before
the patch and any eventual problems after the patch.

The solution in comment #36 above works for me (one comment: ./autogen should be ./autogen.sh).

Before: scroll wheel emulation works before suspend, but broken after suspend.
After: scroll wheel emulation still works after returning from suspend.

Thanks for the patch!

Hi,
autogen.sh quits with the following error:
./configure: line 11656: syntax error near unexpected token `XINPUT,'
./configure: line 11656: `XORG_DRIVER_CHECK_EXT(XINPUT, inputproto)'

btw: i cannot install build-dep. There is no such package. Did I miss something?
Thanx!

Now works for me too!

I was building a deb package with pdebuild and found out that
debian/patches/100_dont_check_abi.patch + Niklas' patch caused scrollwheel emulation to only work in Up direction.

If I disable this patch and use Niklas Vanhainen' patch I get a deb package that fixes this problem.

Thanks.

Aurimas: I don't see that, and you'll need the abi check patch for xinput properties to work at all, so disabling that doesn't seem like a great idea (and certainly wouldn't be acceptable to the X team, I suspect!)

I've attached an i386 deb with the patch included. It would be great if we could get plenty of testing on this patch for potential SRUing

Chris Jones:
tried your package and with it installed scrollwheel emulation works only in Up direction.

Maybe something is wrong with my scrollwheel emulation configuration?
<match key="info.product" string="TPPS/2 IBM TrackPoint">
 <merge key="input.x11_options.EmulateWheel" type="string">true</merge>
 <merge key="input.x11_options.EmulateWheelButton" type="string">2</merge>

 <merge key="input.x11_options.Emulate3Buttons" type="string">true</merge>
 <merge key="input.x11_options.EmulateWheelTimeout" type="string">150</merge>
</match>

Or I simply mess up something while building the package.

It could be your spelling of "Axis" there :)

fwiw I set this stuff from a script in my home directory which I
configured the GNOME Session preferences to launch when I log in.
All it does is run these commands:

xinput set-int-prop DEVICE "Wheel Emulation" 8 1
xinput set-int-prop DEVICE "Wheel Emulation Button" 8 2
xinput set-int-prop DEVICE "Wheel Emulation Y Axis" 8 4 5

where "DEVICE" is "TPPS/2 IBM TrackPoint"

I'm experiencing the same problems as Aurimas Fischer with the don't
check abi patch enabled (including Chris's deb). It does work if I set
it up with xinput, but not with the HAL configuration. This patch is
all about initialization of the device and I assume xinput does its
thing after initialization. I tried including the Y Axis (and other
axises) parameters in the HAL config, unsuccessfully. I will
investigate and report back here.

I get the following error right off the bat:

Ok. I enabled the source repository and successfully installed the patch. I seem to be working great now. Thank you all for your help. I love Ubuntu!

Nicklas: I installed your patch, which fixed the scrolling after suspend issue. However, I am now experiencing the problem of not being able to click and hold my left mouse button (e.g. highlight, drag selection box). I applied the second of your diffs after I found this problem, but it didn't help. I also can't install Chris's package, since it's for the i386 architecture (I'm running 64-bit).

Same problem for myself as well. I have 64 bit ubuntu and so I cannot load Chris' patch.

Not to "beat a dead horse", but the patch (preinit.diff) and process described by Niklas Vanhainen on 2008-11-03 worked (exactly as described) for me on:

Lenovo ThinkPad T61 (type 6465-CTO)

My experience of this bug is different. For instance, just now my middle-button scrolling started working again for no apparent reason. I had been reading email in Thunderbird on one virtual desktop with scrolling disabled. Then I switched to Firefox on another virtual desktop and realised that I was able to scroll properly again. In other words this is happening independently of suspend or resume events. I don't yet know if this also works the other way (i.e.scrolling become suddenly disabled without apparent cause).

Robert: that sounds like a different bug, especially if you have a real middle button and are not using scrollwheel emulation settings. This bug is about xinput settings being lost on resume.

I have applied patch which was mention in comment #36 by Niklas Vanhainen. I have to say that the problem with scolling went gone, but new problem arrived. Left mouse button dragging stops working. I cannot select block of text or drug windows pointing it's title bar. Left mouse button click and double click works fine.
I have ThinkPad T61p and Ubuntu 8.10 x64 with kernel 2.6.27-7-generic.

I have applied also patch from comment #23 and all works perfect now. What I mean is that track point scroll and left mouse dragging works after waking up from suspend. I've tried several times put my computer into S3 mode and wake, and all seems to be working fine.
For the record I'll write all the scriptology that have been applied. I have to install some additional packages (autoconf, libltd7, libtool).

patch1: http://launchpadlibrarian.net/19254960/preinit.diff
patch2: http://launchpadlibrarian.net/18944380/restorewakeup.diff

sudo apt-get build-dep xserver-xorg-input-evdev

patch -p1 < /path/to/patch1/preinit.diff
patch -p1 < /path/to/patch2/restorewakeup.diff
./autogen.sh --prefix=/usr

I hope this will help somebody.

Tomi: use the preinit.diff from comment #27 instead of 22 and 23, it
incorporates both and should apply cleanly, unlike 22 and 23.

You right Niklas. Funny thing that in my comment above (#56) I use link to a proper version of preinit.diff.

Patch confirmed to work on stinkpad X61 using the following:

Kiitos Niklas! Hope we can get this into the package ASAP. I can help out if help will speed things up.

Sammy: There is still the problem with the dont_check_abi patch
causing some problems with the HAL configuration when combined with
this patch, it only works properly using xinput commands. Did you try
patching with dont_check_abi?
I haven't had time to see if this can be fixed somehow. If you would
like to help out, try applying the dont_check_abi patch (i believe
it's in debian/patches of the source tree) to the latest copy from git
to see if the problem has been fixed. If it has, it's only a matter of
identifying which commit fixed it and incorporating that into the
patch.

Niklas: Works with the dont_check_abi patch and git HEAD.

I've just tried running b0737bdbd1f6e601eb4984b6f4cb49279190984c with the dont_check_abi patch and it works for me. Could you confirm i've done the right thing here using the following commands to test it:

As user 'fred' in their home directory:
git clone git://git.freedesktop.org/git/xorg/driver/xf86-input-evdev
cd xf86-input-evdev
git reset --hard b0737bdbd1f6e601eb4984b6f4cb49279190984c
./autogen --prefix=/usr
make

As root:
invoke-rc.d gdm stop
cp ~fred/xf86-input-evdev/src/.libs/evdev_drv.so /usr/lib/xorg/modules/input/
ldconfig -n /usr/lib/xorg/modules/input/
invoke-rc.d hal restart
invoke-rc.d gdm start

Ok... it's not selecting text in any window after applying the b0737* driver. Scrolling works though. I'll check where it fixes it.

Niklas: Here are my findings for the git repository revisions. On some of the revisions I couldn't select text after switching VT and back to X. Selecting by double-click worked but dragging with mouse button down didn't work. In the results below you'll find "Selection" results are about that.

63af314368cec47b6b8266db331f2c820e7a071f CTRL-C kills X, Selections OK, Scroll OK
af096e8c5d8b425f725a37bf4a98e205e70716e9 CTRL-C kills X, Selections OK, Scroll OK
12498042fcc08e34aef0117ce84192f59542fd56 CTRL-C kills X, Selections bad, Scroll OK

As you can see, CTRL-C still kills X even with the HEAD revision (63af314368cec47b6b8266db331f2c820e7a071f). Commit af096e8c5d8b425f725a37bf4a98e205e70716e9 appears to have the fix for the selections breaking after VT switch. Commit 12498042fcc08e34aef0117ce84192f59542fd56 was immediately before af096e8c5d8b425f725a37bf4a98e205e70716e9.

Unfortunately, the commit fixing the problem doesn't cleanly apply to the xserver-xorg-input-evdev-2.0.99+git20080912 source.

Installing the latest xserver-xorg-input-evdev and the xserver-xorg-core package which it depends on from Debian unstable seems to fix the problem.

as a side note, one can restore normal behavior when it's broken by removing and re-modprobing the psmouse module. Not a fix, but at least it doesn't require rebooting or restarting the X server.
(btw the problem happens for me with xserver-xorg-input-evdev 1:2.0.99+git20080912-0ubuntu6.

Hmm, then perhaps it would be a good idea to put in /etc/acpi/resume.d a script (I called mine 99-reload-psmouse):

#!/bin/sh
rmmod psmouse
modprobe psmouse

I think you have to chmod +x it as well.

Confirmed that the instructions from comment 36 work, using the patch from comment 27, on amd64, x200. I modified the steps by removing the explicit autogen, make, make install, and instead doing a debian/rules binary to create a deb.

Then I then saw the same issue that Aurimas reported (HAL policy not working, but xinput lines working); worked around that by adding the following lines to .profile (ugh):

# FIX FOR BROKEN EVDEV/HAL for TrackPoint scrolling:
xinput set-int-prop "TPPS/2 IBM TrackPoint" "Wheel Emulation" 8 1
xinput set-int-prop "TPPS/2 IBM TrackPoint" "Wheel Emulation Button" 8 2
xinput set-int-prop "TPPS/2 IBM TrackPoint" "Wheel Emulation Y Axis" 8 4 5

I consider this preferable to removing and re-adding modules (by pure superstition :). This forms the basis of new documentation added to thinkwiki here:

http://www.thinkwiki.org/wiki/Installing_Ubuntu_8.04_&_8.10_on_an_X200#TrackPoint

If anyone would like to change/improve/correct, please have at it. Thanks everyone!

To add to obsidian's comment #68, it seems that HAL policy file is being read, but it is not being read in correctly. Here are two examples of a line in the policy file and what output from xinput it leads to after reboot:

<merge key="input.x11_options.YAxisMapping" type="string">4 5</merge>
Wheel Emulation Y Axis: 4, 0

<merge key="input.x11_options.YAxisMapping" type="string">5 4</merge>
Wheel Emulation Y Axis: 5, 0

Maybe it is worth filing a bug report about this one if people agree.

should be fixed in jaunty

Niklas's instructions in post #36 at https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-evdev/+bug/282387/comments/36 worked for me after going into standby and resuming.

I am using a Lenovo Thinkpad X61 Tablet.

The only steps additional steps I had to take was the installation of a few other dependencies including libtool and autoconf using the code:

sudo apt-get install libtool
sudo apt-get install autoconf

Thanks a lot, problem seems to be fixed here

This fix works for me on my Thinkpad T61.

Thanks a lot!

So by the status at the top being "fix released" does that mean that the fix should be in the repos already, or do we have to apply the patch as described in #36?

I'm stuck at the 4th step in the sequence:
sudo apt-get build-dep xserver-xorg-input-evdev
apt-get source xserver-xorg-input-evdev
cd xserver-xorg-input-evdev-2.0.99+git20080912
patch -p1 < /path/to/preinit.diff
./autogen --prefix=/usr
make
sudo make install

I get the following error:
laptop:~$ patch -p1 < /path/to/preinit.diff
bash: /path/to/preinit.diff: No such file or directory

I'm running: Intrepid 8.10 64 bit kernel 2.6.27-12 generic Gnome 2.24.1
Any help appreciated!

Nils:
You need to replace "/path/to/preinit.diff" with the actual path to
your preinit.diff.

Works for me on Jaunty α 5 without any patches. My .fdi file for configuration is attached. dmesg says about my trackpoint this:
