Description Dr. Prepper 2022-07-26 17:31:52 UTC 
SUMMARY
Touchpad does not work. It began in 5.24.4 and still happens in 5.25.3 I've had to use the X11 session as a workaround.

The laptop is a Yoga 6 13ARE05.


STEPS TO REPRODUCE
1. Boot to login screen
2. Select Wayland session
3. Login
4. Attempt to move mouse cursor with trackpad

OBSERVED RESULT

Mouse cursor does not move with touchpad input. Touchpad buttons do not cause any action. Touchscreen functions as expected.

EXPECTED RESULT

Touchpad causes mouse cursor to move and touchpad buttons are accepted as input.

Still a problem on 5.26.4

Is there anything else I can provide to help?

Thanks.

Run

  sudo libinput debug-events

use your touchpad, press Ctrl-C, and then attach libinput's output to this bug report

Please open the kwin debug console (by typing "kwin" in krunner) and check if the touchpad is enabled under the input devices tab

kwin debug info for input devices

The touchpad isn't enabled according to the kwin debug input devices section.

If you go into the touchpad settings in system settings, is it enabled there? If not, does enabling it make it work?

That worked! I'm not sure why the touchpad was disabled for wayland sessions.

I apologize for not looking there before.

thanks. Not sure why it would be disabled by default either, but unless more people experience the same issue I think we can close this bug
