Synaptics touchpad buttons stopped working (regression)

[Mason]

Occurs on HP Pavilion DV6 laptop
Ubuntu 10.04

Symptoms: Laptop touchpad lost button functionality after kernel update.
Tapping still works as left button press, but left, middle and right button standard functionality no longer working. Note that the touchpad has the buttons as part of the pad.
From the excerpts of the working and non-working dmesg, it looks like "clickpad mode" is no longer enabled. Perhaps this will help in fixing this bug in Ubuntu.

[Mason (mlt-svn)]

Just had kernel package 2.6.32-34-generic update, and...the problem still exists.
Hopefully the Ubuntu devs have some time to look at this!

[Mason (mlt-svn)]

Just tried the kernel package upgrade to 2.6.32-35-generic. Unfortunately the problem still exists.
Furthermore, I cannot seem to make any setting in synclient fix this.
Any suggestions for something to try?

[Mason (mlt-svn)]

Kernel package 2.6.32-36-generic: problem still exists.
Is this the wrong place to report this problem?

[Mason (mlt-svn)]

Kernel package 2.6.32-37-generic: problem still exists.
Windows 7 works fine--should this bug be linked to bug #1?

[Mason (mlt-svn)]

Kernel package 2.6.32-38-generic: no surprise now, the problem still exists.
Regressions are a low priority?

[Joseph Salisbury (jsalisbury)]

Would it be possible for you to test the latest upstream kernel? It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.3 kernel[1] (Not a kernel in the daily directory). Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag(Only that one tag, please leave the other tags). 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.

If this bug is fixed by the mainline kernel, please add the following tag 'kernel-fixed-upstream-KERNEL-VERSION'. For example, if kernel version 3.3-rc2 fixed the issue, the tag would be: 'kernel-fixed-upstream-v3.3-rc2'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

[Mason (mlt-svn)]

Tested with both
linux-image-3.3.0-030300rc3-generic-pae_3.3.0-030300rc3.201202082335_i386.deb and
linux-image-3.3.0-030300rc4-generic-pae_3.3.0-030300rc4.201202181935_i386.deb

Both still exhibit the problem.

[Joseph Salisbury (jsalisbury)]

This issue appears to be an upstream bug, since you tested the latest upstream kernel. Would it be possible for you to open an upstream bug report at bugzilla.kernel.org [1]? That will allow the upstream Developers to examine the issue, and may provide a quicker resolution to the bug.

If you are comfortable with opening a bug upstream, It would be great if you can report back the upstream bug number in this bug report. That will allow us to link this bug to the upstream report.

[Mason (mlt-svn)]

There is apparently a report already for this bug in bugzilla, #41252:
https://bugzilla.kernel.org/show_bug.cgi?id=41252

The response to that bug indicates the kernel had clickpad support removed, and it was supposed to be moved to the x driver (to xf86-input-synaptics).

Following the trail to the xorg bugtracker:
https://bugs.freedesktop.org/show_bug.cgi?id=38303

it appears the bug has been fixed as of Feb. 9.

So I think this means it is back to Ubuntu!
Will the Ubuntu devs be able to integrate the fix in the xorg input driver?

Many thanks!

[Joseph Salisbury (jsalisbury)]

The fix will make it into Ubuntu through stable updates, once it is applied to the upstream stable tree.

[Mason (mlt-svn)]

Great!
Should this bug have additional tags to indicate it is an xorg input bug? Or be switched to an appropriate xorg group in ubuntu?

[EboMike (0-launchpad-ebomike-com)]

As of Ubuntu 12.04 with 3.2.0-27-generic, this is still an issue. Is there any way to check whether or not xorg contains the patch?

[penalvch (penalvch)]

Mason, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.11-rc5

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.
