Touchpad incorrectly detected as PS/2 mouse in 'ASUS PU551L'

[David Zafra Gómez]

As I've just red here https://wiki.ubuntu.com/DebuggingTouchpadDetection, I'm sending you this information. My case fits with what is described in "In case Touchpad features like scrolling, tapping, etc. do not work at all.", that is, I can't find the 'Touchpad' tab in System -> Preferences -> Mouse. Also, the touchpad acts just like a mouse, and I can't disable it.

I've attached devices text file as suggested in the link above, but I haven't been able to attach xinput and Xorg.0.log files because I just can't attach one file.

Thanks for dealing with my case.

Hi Christopher

First of all, I want to thank you for your help.

I have updated BIOS but nothing seems to happen.

If I run
    sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
it shows
    PU551LA.208
    10/22/2014

What can I do now?

On the other hand, when you say "Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful", do you mean I have to change anything in the bug description?

Regards,

David Zafra

Dear Christopher

I've installed 4.0.0-040000rc6-generic kernel for amd64 but I'm afraid this kernel does not fix this bug.

Thanks again for your support.

David Zafra Gómez, the issue you are reporting is an upstream one. Could you please report this problem to the appropriate mailing list (linux-input) by following the instructions verbatim at https://wiki.ubuntu.com/Bugs/Upstream/kernel ?

Please provide a direct URL to your e-mail to the mailing list once you have made it so that it may be tracked via http://vger.kernel.org/vger-lists.html . It can take a day for the new e-mail to show up in the respective archive.

Thank you for your understanding.

[David Zafra Gómez (dezeta)]

Dear Christopher

I'll do what you suggest.

Anyway, I add this information if it's helpful.

An error appears now in the notification bar. Its in Spanish, and here is my translation:
"An error happened. Run the update manager [...].
 The error message is: Error BrokenCount > 0.
 Normally, this means that you have installed packets whose dependencies haven't been satisfied."

Thanks for your support. It's so fast!

Dear Christopher

Here is the link to my email in the mailing list:
http://www.spinics.net/lists/linux-input/msg38000.html

It seems nobody is dealing with it :-(

Cheers.

David Zafra Gómez, unfortunately, these types of issues tend to take quite a bit of time to develop fixes for (tending towards weeks to months, versus days to weeks). Also, upstream is a lot busier than many, so they may have been pulled in other directions. You would want to continue to keep this report relevant by testing any new upstream kernel that come out and report the results here.

[David Zafra Gómez (dezeta)]

OK Christopher, thanks for you support. I sent a reminder and then they
asked. We are debugging the error :-) .

Hello again

I've been asked to apply a patch to the source code of the kernel and build it.

I'm afraid I haven't built a kernel before, so I would thank you if you could help me.

I've installed kernel 4.0.0-040000rc6.201503291935. I've jus attached the patch they sent to me.

Tanks in advance

David Zafra

David Zafra Gómez, please see https://wiki.ubuntu.com/Kernel/KernelBisection#Testing_a_newly_released_patch_from_upstream .

[David Zafra Gómez (dezeta)]

It worked like a charm!!

Now I can use all advanced touchpad features.

Thank you very much to Hans de Goede, Benjamin Tissoires (Linux Kernel) and Christopher M. Penalver!!

Then, I'm afraid that if I install new kernel updates the fix will be removed. Is this correct? I've patched 3.13.0-53-generic kernel.
