Comment 37 for bug 1938096

I also confirm this bug - Lenovo Thinkpad P1 Gen2.
uname: Linux zzzzz 5.11.0-27-generic #29~20.04.1-Ubuntu SMP Wed Aug 11 15:58:17 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux
touchpad: Bus 001 Device 003: ID 06cb:00bd Synaptics, Inc.
Nothing alarming in logs.

The touchpad affected by this bug feels like "lagging".
Sweep and tap actions (without hard touchpad pressing) work after multiple tries.
Also, I noticed "quick" suspend and resume does not cause the bug.
It's necessary to let laptop stay suspended quite of time - in my case it was couple of hours - I didnd't try to narrow it.

UPDATE: Funny thing, hybernating to disk and waking up restores touchpad funtionality.
