Subject: Confirmed on Dell Laptop - Wayland Session / libinput issue
I can confirm I am experiencing this same issue on my Dell laptop.
Symptoms:
* Touchpad clicks (both physical and tap-to-click) are registered correctly.
* Touchpad pointer motion does not work at all.
Diagnostics:
I've done some debugging and found the following:
* Running evtest on the touchpad's device node (/dev/input/event*) shows
that the kernel is correctly
receiving motion events with axis data.
* However, running libinput debug-events --show-keycodes shows no events
when attempting to move the
pointer. It only shows events for clicks.
This suggests the issue lies between the kernel and libinput.
Environment:
This bug occurs in the default "Ubuntu" Wayland session.
Given that this issue is specific to Wayland and the diagnostic tools point
to libinput not processing
the events, I suspect this bug may be more appropriately filed against the
gnome-shell (as the Wayland
compositor) or libinput package directly, rather than
xserver-xorg-input-libinput?
