[MacBookPro8,2] Trackpad single clicks nearly always double clicks

[Lars Noodén]

On a MacBookPro8,2, the track pad does not respond properly. Single clicks are nearly always interpreted as double clicks.

Hello Lars
Seems to me something kernel related, so can you please reproduce the bug and type in a terminal:
apport-collect 881830
Can also be useful take a look at others log, then please attach here, using the button below 'Add attachment or patch' the file

[Andy Whitcroft (apw)]

Does this problem occur when running with official ubuntu kernels? We do have a number of mouse/touchpad fixes in our tree.

[Lars Noodén (larsnooden)]

Yes, the problem occurs with the official Ubuntu kernels. It also occurs with the Mainline kernels.
http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/current/

[Brad Figg (brad-figg)]

Thank you for taking the time to file a bug report on this issue.

However, given the number of bugs that the Kernel Team receives during any development cycle it is impossible for us to review them all. Therefore, we occasionally resort to using automated bots to request further testing. This is such a request.

We have noted that there is a newer version of the development kernel than the one you last tested when this issue was found. Please test again with the newer kernel and indicate in the bug if this issue still exists or not.

If the bug still exists, change the bug status from Incomplete to Confirmed. If the bug no longer exists, change the bug status from Incomplete to Fix Released.

If you want this bot to quit automatically requesting kernel tests, add a tag named: kernel-bot-stop-nagging.

 Thank you for your help, we really do appreciate it.

[Lars Noodén (larsnooden)]

Present in both newest kernels:

- 3.1.0-999-generic #201111070407 SMP Mon Nov 7
  09:08:05 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux

- 3.1.0-2-generic #3-Ubuntu SMP Fri Oct 28
  20:28:07 UTC 2011 i686 i686 i386 GNU/Linux

[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 . If possible, please test the latest v3.2-rcN 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 others). 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 3.2-rc1 fixed and issue, the tag would be: 'kernel-fixed-upstream-v3.2-rc1'.

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

Thanks in advance.

[1] http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.2-rc2-oneiric/

[Lars Noodén (larsnooden)]

The problem still exists in the new mainline kernel:

$ uname -a
Linux xubuntu 3.2.0-999-generic #201111170405 SMP Thu Nov 17 09:07:10 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux

[Lars Noodén (larsnooden)]

It's still not possible to click-and-drag

[Lars Noodén (larsnooden)]

Still present in Precise:

$ lsb_release -rd
Description: Ubuntu precise (development branch)
Release: 12.04

[Lars Noodén (larsnooden)]

In one kernel, the trackpad does not respond at all:
Linux 3.2.0-1-generic #3-Ubuntu SMP Tue Nov 22 11:30:27 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux

[Lars Noodén (larsnooden)]

In a recent kernel, the track pad responds partially. It is not possible to click-and-drag and single clicks are often interpreted as double clicks.

Linux xubuntu 3.2.0-999-generic #201112040405 SMP Sun Dec 4 09:06:01 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux

[penalvch (penalvch)]

Lars Noodén, 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 the latest upstream kernel available? It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please do not test the kernel in the daily folder, but the one all the way at the bottom. 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. As well, please comment on which kernel version specifically you tested.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

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', and comment as to why specifically you were unable to test it.

Please let us know your results. Thanks in advance.

[Lars Noodén (larsnooden)]

It's still a problem in 12.10beta though less severe. The movement is jittery and hops. When typing on the keyboard, rapid bursts are often misinterpreted as mouse clicks even though the trackpad was not touched. What further data can be collected?

[penalvch (penalvch)]

Lars Noodén, I refocused this bug down to one of your two trackpad problems as per https://wiki.ubuntu.com/Bugs/BestPractices#X.2BAC8-Reporting.Focus_on_One_Issue . While a fix for one could fix the other, we would want to treat the two issues of single clicks are treated as doubles most of the time, and how click-and-drag does not work seperate for now.

Also, while booted into the Ubuntu repo kernel, could you please execute the following at a terminal:
apport-collect 881830

As well, could you please provide the information following https://wiki.ubuntu.com/DebuggingTouchpadDetection#In_case_at_least_one_of_Touchpad_features_works_but_does_not_work_correctly_and_as_expected ?

Thank you for your understanding.

Trouble collecting apport information. Sorry for duplicates.

The double click problem seems now to be one where it single clicks occasionally when typing on the keyboard regardless of whether there is any contact with the mouse or trackpad.

[Lars Noodén (larsnooden)]

I don't see where the tags are or can be added.

[penalvch (penalvch)]

Lars Noodén, getting back to https://bugs.launchpad.net/ubuntu/+source/linux/+bug/881830/comments/87 , the bisect documentation has been updated to advise switching to bisecting the mainline kernel instead. Hence, could please resume your bisect via https://wiki.ubuntu.com/Kernel/KernelBisection ?

[Lars Noodén (larsnooden)]

With the 3.11.0-4-generic #9-Ubuntu SMP kernel that is part of Saucy, the errant mouse clicks are less of a problem. They seem not to be present any more when just using the trackpad, but still a problem when typing. Is a bisection still needed? If so between which kernels?

[penalvch (penalvch)]

Lars Noodén, please see http://kernel.ubuntu.com/~kernel-ppa/info/kernel-version-map.html .

[Lars Noodén (larsnooden)]

Christopher, thanks. What should I look at from that page?
