Given the nvidia drivers are a WORKAROUND, it appears the touchpad not

1) I've been using the drivers from NVIDIA with the normal (not
mainline) kernel 4.13.0-32 for the past week and haven't had this
touchpad issue.
2) When I resume from suspend the touchpad either works or it doesn't.
It always stops working after I suspend/resume a few times. How much

Sergey Zolotarev, to clarify, let us focus on the timeframe from since
you installed Ubuntu a couple weeks ago to present.
1) To advise, it wouldn't hurt to see how things change when you use the
nvidia proprietary driver. However, you will want to use the Ubuntu
kernel (not mainline) before
I installed Ubuntu on this laptop a couple of weeks ago, so I can't say.
But before Ubuntu I was using Fedora 27 for around 2 months and I didn't
experience this problem there.
I'm attaching dmesg output after another touchpad incident, from 4.15.1

This patch worked for me with v4.15 kernel:
https://paste.ubuntu.com/26496011/
I basically found the old patch and added an entry for K501UQ there. The

Sergey Zolotarev, to advise, reports focus on one issue per report. This
report is scoped to touchpad not working after suspend, not everything

have.
Despite this, could you please provide the missing information from
I installed the latest kernel (4.15) from http://kernel.ubuntu.com
/~kernel-ppa/mainline/v4.15/ but it didn't help. Touchpad worked for a
few seconds after wakeup but then it stopped working. Also same issue
with reboot again, don't know why you deleted it.
