I upgraded to Ubuntu 22.04 recently, from 21.10, and ran into the same problem I had since ubuntu introduced wayland by default: my touchpad and keyboard do not work on wayland.I have an Asus laptop with touchpad, keyboard and touchscreen. Wayland actually recognises the touchscreen, so I can get past GDM by typing my password with the screen (and chosing Xorg as a session). However, as I feel Xorg will be deprecated soon and I do not see any fix, I need your help to get my input devices working on wayland.
I tried installing libinput-tools and looking at the recognised devices, where I do see my touchpad and keyboard. Also, running libinput debug-events does show pad, mouse, keyboard.
I do not seem to find documentation on how to look into the process of device recognition by wayland (especially not for the GDM login screen), and I admit it is difficult to troubleshoot from wayland using only touchscreen...
Happy to have some clues on how to gather more info and file a proper bug report.
Needless to say, all input devices work perfectly under Xorg, so no hardware nor kernel issue.
