[Asus X455LD] Elantech touchpad stops working after suspend

[Harris Anggara]

i have asus a455ld i5 5200u running kubuntu 15.04 with kernel 4.0.8-040008-generic.
touchpad is recognized as elantech version 4. everything was fine until my notebook go to suspend and resume without touchpad working.
I tried :
modprobe -r psmouse
modprobe psmouse

it only work before suspend.
execute those commands after resume from suspend is not working.

the last thing i tried is this.

when i use this command before suspend :

insmod /lib/modules/4.0.8-040008-generic/kernel/drivers/input/mouse/psmouse.ko

these appear in the dmesg:

[ 820.207105] psmouse serio1: elantech: assuming hardware version 4 (with firmware version 0x381f00)
[ 820.222270] psmouse serio1: elantech: Synaptics capabilities query result 0x10, 0x14, 0x0e.
[ 820.294698] input: ETPS/2 Elantech Touchpad as /devices/platform/i8042/serio1/input/input146

but when i use the command after suspend, there is nothing any output in the dmesg.

i tried all ubuntu varian and opensuse 13.2 live usb, the result is the same.
but in windows 10, touchpad still active after suspend.

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.2 kernel[0].

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'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

[Harris Anggara (harrisanggara)]

kernel 4.2 doesn't fix this issue.

[Harris Anggara (harrisanggara)]

this issue start happening since i bought this laptop and installed ubuntu 15.04 on this. i also tried ubuntu 14.04 but this issue still exist.
i dont remember how many kernel i tried but none of them can solve this issue.

note: modprobe psmouse will bring the psmouse module back (checked in lsmod result) but touchpad still freezing.

[penalvch (penalvch)]

Harris Anggara, while booted into a Ubuntu kernel (not upstream one) please execute the following command, as it will automatically gather debugging information, in a terminal:
apport-collect 1490130

[Daniel Drake (dsdrake)]

My colleague found this on a similar laptop, I suspect it is the same issue: http://marc.info/?l=linux-input&m=144312209020616&w=2

[Thatoo (thatoo)]

Hello, I have the same problem.
I found this thread, http://ubuntuforums.org/showthread.php?t=2182922&page=2 that gave a solution to a similar problem :
create a file here /etc/pm/sleep.d/0000trackpad
sudo gedit /etc/pm/sleep.d/0000trackpad

and add the following
#!/bin/sh
case "$1" in
    suspend|hibernate)
         modprobe -r psmouse ;;
    resume|thaw)
        modprobe psmouse ;;
esac

it didn't work at first because of the double " ; " so I changed it to
#!/bin/sh
case "$1" in
    suspend|hibernate)
        modprobe -r psmouse;
    resume|thaw)
        modprobe psmouse;
esac

and now, the computer refuse to sleep. At least, the touchpad keep working so it does something but I can't make my conputer sleepin...

By the way, if it gives a clue, I can deactivate and activate again the touchpad with the hotkey of my keyboard.

[Harris Anggara (harrisanggara)]

hello Daniel, thanks for your suggestion. that works ! :)
now i'm using kernel 3.19 with the patch. i changed the DMI_PRODUCT_NAME with X455LDB (because that is my laptop model)
thank you verry much.

hello thatoo, i already tried that and no result. the psmouse module loaded after suspend, but touchpad still not working.

[penalvch (penalvch)]

Thatoo, it will help immensely if you file a new report via a terminal:
ubuntu-bug linux

Please feel free to subscribe me to it.

Harris Anggara, could you please advise to https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1490130/comments/7 ?

[Thatoo (thatoo)]

@Christopher M. Penalver (penalvch), here is the answer of
ubuntu-bug linux

It appears you are currently running a mainline kernel. It would be better to report this bug upstream at http://bugzilla.kernel.org/ so that the upstream kernel developers are aware of the issue. If you'd still like to file a bug against the Ubuntu kernel, please boot with an official Ubuntu kernel and re-file.

So I file a bug on http://bugzilla.kernel.org/
https://bugzilla.kernel.org/show_bug.cgi?id=105231

Before you read it, I'm sorry to say that I made a mistake, I confuse Elantech and Focaltech.
It seems that my touchpad is a Focaltech not an Elantech but I'm not exactly sure how to know, I've just find out in this file /proc/bus/input/devices .

Regards,

[Thatoo (thatoo)]

Harris Anggara (harrisanggara), could you explain me with some detail what did you do to make this patch work?
What text did you add?changed?removed? in which file (I can't file any drivers/input/serio/i8042.c)?
And how can I know what I should replace X455LDB for?

Regards,

[Thatoo (thatoo)]

sorry, I meant I can't find any "drivers/input/serio/i8042.c" file.

[Harris Anggara (harrisanggara)]

Hello thatoo, i compiled the kernel for myself with the patch that given by daniel. this is the instruction i followed https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel
"drivers/input/serio/i8042.c" file only exists on the kernel source.
lines with "+" at first character are the patch that you should modify or add to "drivers/input/serio/i8042.c" file.
to identify your laptop model you can run
sudo dmidecode | grep Product\ Name

btw, i'm sorry for my english, not my native language.

Harris Anggara, could you please test the latest upstream kernel available from the very top line at the top of the page from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D (the release names are irrelevant for testing, and please do not test the daily folder)? Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds . This will allow additional upstream developers to examine the issue.

If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ

Where X, Y, and Z are numbers corresponding to the kernel version.

If the mainline kernel does not fix the issue, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ

Please note, an error to install the kernel does not fit the criteria of kernel-bug-exists-upstream.

Once testing of the latest upstream kernel is complete, please mark this report's Status as Confirmed. Please let us know your results.

Thank you for your understanding.

[Thatoo (thatoo)]

Thank you so much Harris Anggara (harrisanggara), it works for me with the kernel 4.2 for ubuntu 14.04. No drivers needed and I can suspend my computer.

[Thatoo (thatoo)]

I had to change DMI_PRODUCT_NAME with K501LX by the way.

[Harris Anggara (harrisanggara)]

Christopher M. Penalver (penalvch) , i tried kernel 4.3 and still can not use the touchpad after suspend.
i heard dell xps 13 developer edition also had this issue, but they already fixed that by provide .deb package.

[penalvch (penalvch)]

Harris Anggara, could you please capture the missing information following https://wiki.ubuntu.com/DebuggingKernelSuspend .

[Wladimir Mutel (mwg)]

I have Asus X302LA notebook, and 'modprobe -r psmouse' followed by 'modprobe psmouse' makes its touchpad die off even without doing pm-suspend
Also I see in dmesg that ETPS/2 Elantech touchpad is initially created as /devices/platform/i8042/serio1/input/input5, and after module reload, it is recreated as .../input292 (but only after first module re-probe, next times nothing happens at all)
The script in /etc/pm/sleep.d apparently does not do anything (probably need to re-test it after a fresh boot)

[Wladimir Mutel (mwg)]

some records from my dmesg :

Harris Anggara, can you please write how the "drivers/input/serio/i8042.c" file has to look after the changes (or upload your version)? I don't exactly understand how to apply the patch provided by Daniel.

[Marco Russo (russomarco)]

And also what to do after to install the new modified kernel.

[Erik Hoekstra (hoekstra)]

Funny thing.

Reboot Ubuntu, don't login. Let the device go to hibernate/sleep.

After awaking the device the mouse still works. So this seems to only happen, after a user logged in.

[Harris Anggara (harrisanggara)]

Hei Christopher M. Penalver (penalvch), i'm sorry i can't give any log file or test anything that takes some times since i have a lot of project to do with this notebook.

[Mihkel Tõnnov (v6lur)]

Patch from #8 solved this issue for me on Asus K501LX with Mageia, kernel 4.4.8.

Linus just picked the today's input PR with a fix for this problem for A455LD, X455LDB, K501LB, K501LX and X302LA.

Can you please check this patchset: http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=689f891c980949d3eb64f61651db53cb347e0a13 ?

If you have a different model, that needs to be included is this list, please tell us here in the kernel bug: https://bugzilla.kernel.org/show_bug.cgi?id=107971

Please, let me know if this fixes your problem.

Thanks!

[Harris Anggara (harrisanggara)]

i will try it and report the result as soon as posible. thank you very much.

[Harris Anggara (harrisanggara)]

I just cloned and compiled the latest commit. I can confirm it works and my touchpad problem is solved without applying any patch. Thank you very much.

[penalvch (penalvch)]

Harris Anggara, to advise, an upstream patch working for you wouldn't fit the definition of Fix Released for linux (Ubuntu) as per https://wiki.ubuntu.com/Bugs/Status .

Despite this, it would be helpful to confirm if the patch noted by Marcos Paulo de Souzas indeed fixed your issue. Instructions are available via https://wiki.ubuntu.com/Kernel/KernelBisection#Testing_a_newly_released_patch_from_upstream .

Could you please advise?

[Ivnitskii Andrei (ivnitsky-a)]

Hi! Same problem. I install kernel 4.8 in Ubuntu 16.04 (from official repos) and problem solved! Try this too.

[Wladimir Mutel (mwg)]

It should have been fixed with kernel package v. 4.8.0-27 and later

[Sergey Zolotarev (szx)]

Same problem with ASUS K501UQ on 17.10. I don't see this model in the list of "matches" in the patch, so I guess I should add it manually and see if that works.

[penalvch (penalvch)]

Sergey Zolotarev, it will help immensely if you use the computer the problem is reproducible with, and provide necessary debugging logs by filing a new report with Ubuntu via a terminal:
ubuntu-bug linux

Please feel free to subscribe me to it.

[Marcos Paulo de Souza (marcospsouza)]

I think the bug was fixed since the patch changed over time and now it looks for all ASUS laptops in order to skip selftests:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=77b425399f6d5f1b04c58738bc10ca6decb10c9a

Sergey Zolotarev, can you please test again with a recent kernel and tell us if the issue was fixed? It should work with every modern ASUS laptop, so everyone who commented in this bug, please test against a newer kernel release.

Thanks
