I've got a Thinkpad X1 Carbon Gen 9.
When I hibernate on Ubuntu 21.10 or Pop!_OS 21.10 or Manjaro, the touchpad either stops working after resume or the cursor moves very choppy. Both with Wayland and xorg. Kernel on Ubuntu 21.10: 5.13.0-22.22; Pop!OS: 5.15.5-76051505-generic; Manjaro - unsure. I'm using Gnome.
Looking for a way to fix this, so that the touchpad is fully working post-resume.
I tried reloading the kernel module with:
sudo rmmod psmouse; sleep 2; sudo modprobe psmouse I also tried dis-/enabling the xinput device:
xinput disable 'SYNA8008:00 06CB:CE58 Touchpad'; sleep 2; xinput enable 'SYNA8008:00 06CB:CE58 Touchpad' And I also tried removing/loading the i2c_hid kernel module per touchpad not working after hibernate. I doubt that this actually did anything, to be honest. I used "solution 2":
$ cat /etc/systemd/system/root-resume.service [Unit] Description=(un)load module i2c_hid when going to/from sleep Before=sleep.target StopWhenUnneeded=yes [Service] Type=oneshot RemainAfterExit=yes ExecStart=modprobe -r i2c_hid ExecStop=modprobe i2c_hid [Install] WantedBy=sleep.target In syslog (Pop!_OS):

With xinput test 'SYNA8008:00 06CB:CE58 Touchpad' I can see, that there ARE signals received when I use the touchpad. Compared to pre-hibernate, there are A LOT less signals.
The "joystick" "mouse" always works. But I am not compatible with the knob ;)
