Touchpad on Gigabyte T1005 not working without extra kernel parameter

[Marius B. Kotsbak]

In current natty alpha 3, the touch screen works properly, but the traditional touch pad does not work at all. Not sure if this is by design (touchpad and touchscreen interfering with each other) or is a bug. I would like to have both working (touchpad relative and touchscreen absolute positioning).

Mouse pad still does not work latest Precise and in kernel 3.4-rc4 (package linux-image-3.4.0-030400rc4-generic).

WORKAROUND: the fix is to add this kernel parameter: 'i8042.noloop=1'.

 I recognize that the touch pad is not listed here (just the touch panel):

$ xinput -list

[ 73.390] (EE) no touch for emulated button press

[Marius B. Kotsbak (mariusko)]

Is it using synaptics? I thought not, but evdev.

But anyway, I think this is caused by that I forgot (as the touchscreen worked) the workaround described here:

https://help.ubuntu.com/community/GigabyteT1005

Is there any way we can have this work out of the box? Alternatively easily selected in the startup menu.

[Bryce Harrington (bryce)]

Hmm, there is a touchpad listed in peripherals.txt but I don't know if that's significant at all. Certainly there's no sign of it in the Xorg.0.log, which there *should* be if the kernel is exposing the device.

What does the output of `sudo lsinput` look like?

[Marius B. Kotsbak (mariusko)]

Well, the fix is to add this kernel parameter: 'i8042.noloop=1' so it is probably a kernel module issue? See bug #87262, it is reported against the kernel package.

[Bryce Harrington (bryce)]

bug #87262 is pretty ancient, I doubt it's at all relevant.

However, I do agree it's likely this is a kernel bug. I'll refile it there; Chase can correct it if I'm wrong.

In any case, we still need to see your `sudo lsinput` output.

[Chase Douglas (chasedouglas)]

I concur, looks like a kernel bug.

[Marius B. Kotsbak (mariusko)]

Okay, I set this to confirm as it is noted in the wiki page for the netbook as well as in the forum.

[AF (shuffle)]

i8042.noloop=1 Works for the T1125N thanks Marius.

An aside: how should I enable multitouch on my touchscreen?

Thanks

[penalvch (penalvch)]

Marius Kotsbak, thank you for reporting this and helping make Ubuntu better. 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? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

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

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

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . 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.

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'.

Please let us know your results. Thanks in advance.

[Marius B. Kotsbak (mariusko)]

Mouse pad still does not work without this kernel parameter in both latest Precise and in kernel 3.4-rc4 (package linux-image-3.4.0-030400rc4-generic).

[Marius B. Kotsbak (mariusko)]

AF (shuffle): what is not working with multitouch? You maybe need to run the "ginn" application?

Marking Triaged Low as mainline tested and this is a bug that has an "easy work-around".

[penalvch (penalvch)]

Marius Kotsbak, the issue you are reporting is an upstream one and it would be nice if somebody having it could send the bug to the developers of the software by following the instructions verbatim at https://wiki.ubuntu.com/Bugs/Upstream/kernel . If you have done so, please tell us the number of the upstream bug (or the link), so we can add a bugwatch that will inform us about its status. Thanks in advance.

[Marius B. Kotsbak (mariusko)]

There is actually an upstream bug report about this exact hardware.

[AF (shuffle)]

Update: After updating to 12.04, touchpad is completely lost (i8042 fix does not work anymore).
Touchscreen continues to work fine, but touchpad is completely gone, despite all i8042.noxxx grub entries...

Anybody else suffer this fate, or have similar problems?

[Marius B. Kotsbak (mariusko)]

I had no problems like this after upgrading. If you don't solve it, I would recommend a reinstall, or install over the old but keeping the partitions unformated. Does it work running the live CD using the kernel parameter?

Anyway, it seems like the upstream fix is trivial. Maybe I can try to make a patch if I get time.

[AF (shuffle)]

Thanks Marius, I'll give the Live CD + Kernel Parameter a shot.
Rats. Linux almost becomes easy and then a small thing becomes a large thing. (no CD Drive on this laptop)
I'll test it and come back.
Thanks

[penalvch (penalvch)]

AF, please execute the following via the Terminal and feel free to subscribe me to it:
ubuntu-bug linux

Thanks!

[Marius B. Kotsbak (mariusko)]

AF (shuffle): could you please post the output of "sudo dmidecode" on the T1125N? Then we might add out of box support for that one too in the kernel.

[Dmitry Torokhov (dtor)]

Anyone needing i8042.noloop to get their touchpad working may send output of "sudo dmidecode" directly to <email address hidden> with a short descrition of their laptop.

Thanks!

[Marius B. Kotsbak (mariusko)]

The attached patch worked fine applied to the Ubuntu Precise kernel git branch.

[Marius B. Kotsbak (mariusko)]

Fixed upstream and im stable backports, so hopefully this will be in Ubuntu updates and in the new Ubuntu releases.

[Marius B. Kotsbak (mariusko)]

Fixed in commit 996ab492443658e15b0a6b912ed703411e005475, which is in linux 3.5.4 and Ubuntu kernels:

Ubuntu-3.5.0-15.20
Ubuntu-3.5.0-15.21
Ubuntu-3.5.0-15.22
Ubuntu-3.5.0-211.18

[Marius B. Kotsbak (mariusko)]

Verified this is fixed in current Quantal kernel version. Stable backport should ensure this is going to be fixed in earier Ubuntu versions soon too.
