[Uros Trojar]

Touchpad not working after suspend/resume on Asus X302LA.

I have tried both workarounds in bug #1393079 to no success.

Uros Trojar, in order to allow additional upstream developers to examine the issue, at your earliest convenience, could you please test the latest upstream kernel available from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D ? Please keep in mind the following:
1) The one to test is at the very top line at the top of the page (not the daily folder).
2) The release names are irrelevant.
3) The folder time stamps aren't indicative of when the kernel actually was released upstream.
4) Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds .

If testing on your main install would be inconvenient, one may:
1) Install Ubuntu to a different partition and then test this there.
2) Backup, or clone the primary install.

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, and Y are the first two numbers of the kernel version, and Z is the release candidate number if it exists.

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.

Also, you don't need to apport-collect further unless specifically requested to do so.

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

Thank you for your understanding.

Which part of the process does the issue occur with, the suspend to ram, or resuming from?
Resuming from

Please advise how you suspended specifically. (all apply)
    Executing at a terminal pm-suspend
    Shutting the lid of your laptop, which is set to suspend on close.
    Clicking the word Suspend in the GUI.
    The computer suspends automatically on inactivity.

Please advise how you resumed specifically. Doesn't matter. Check already attached logs.

    Pressed the power button
    Lifted the lid

[penalvch (penalvch)]

Uros Trojar, to clarify, on which of the attached dmesg files is this problem reproducible with?

Also, the latest mainline kernel is now 4.6-rc2. You don't have to reattach everything, just test once to see if still reproducible or not, and then advise.

[Uros Trojar (uros-trojar)]

Hi Christopher,

I've upgraded to rc2 and the problem is still there. I've run sudo sh -c "sync && echo 1 > /sys/power/pm_trace && pm-suspend" immediately after reboot into rc2 and the trackpad went dead.

[penalvch (penalvch)]

Uros Trojar, to clarify, on which of the attached dmesg files is this problem reproducible with?

Also, please continue to test the latest mainline kernel (now 4.6-rc4) to keep this report relevant to upstream.

[Uros Trojar (uros-trojar)]

Christopher, can you clarify. Do you need ALL of the dmesg files or just one? I can provide you with one relevant for rc4 if all of the specified confuses you.

[penalvch (penalvch)]

Uros Trojar, all of them (i.e. don't skip anything).
