Touchpad stopped working after hibernate on Thinkpad X1 Carbon with Ubuntu and Pop!_OS 21.10

  • 772

Having issues with my Thinkpad X1 Carbon Gen 9.

When I hibernate Ubuntu 21.10 (or also Pop!_OS 21.10 - I've got multiple installations on the system), the touchpad stops working. Both with Wayland and xorg. Kernel on Ubuntu 21.10: 5.13.0-22.22. I'm using Gnome.

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'

No chanes.

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 ;)

  1. HEUREKA!

    For whatever reason, suspend was set to "S3 Linux" in the BIOS. After changing it to "Windows/Linux", the touchpad seems to be working just fine after a wakeup.

    Ah… What a relief ;) Now the device is so much more useful ;)
