Public bug reported:
Hardware: Thinkpad X1 Carbon, 9th generation
Touchpad: SYNA8009:00 06CB:CE57
Right after a clean reboot, the touchpad works fine. No issues
whatsoever. But after resuming from even its first suspend after a clean
boot, the touchpad feels less responsive, choppy or even laggy. Very
strange. I have tried removing and re-inserting some HID kernel modules,
"psmouse", and setting i915.psr_enabled=0 in kernelstubs. Haven't found
anything that fixes it yet. The trackpoint works flawlessly all the
time, so that is the current backup when I don't have an external mouse
connected.
My installed OS is Pop!_Os 21.04, but I have tested and confirmed this
on a live USB with Ubuntu 21.04 as well and the issue do present itself.
I have also tried upgrading to the latest 5.13.5 and 5.14.0rc2 kernels
from the mainline PPA, and even tried bumping the libinput10 to 1.18.0
from the impish repos today to no avail I'm afraid.
