Touchpad not recognized anymore

Hey folks,

my touchpad stopped working, most likely after plugging my laptop into a docking-station which had a bluetooth remote keyboard+touchpad connected. Not working means it doesn’t recognize any input and the corresponding config section disappeared from the gnome config GUI. However, running a live system shows, that it’s not the hardware. Plugging out both docking-station and/or bluetooth dongle, or rebooting in those states didn’t show any effect. I’d be very happy if someone had an idea what to try next…

The MS Nano Tranceiver entries seem to be related to the remote keyboard/touchpad (dissapear when disconnected):

Find your touchpad id in:

$ xinput list


$ xinput list-props <touchpad id>

ensure Device Enabled (<note this number>) has value 1, if not:

$ xinput set-prop <touchpad id> <that noted number or "Device Enabled", yes in quotes> 1

Thanks a lot for your reply. I checked the props for all listed devices via ‘xinput list’, starting with pointers but also for the keyboard entries (id 2-9). All of them have value 1 for the “device enabled” property.
Please excuse, I’m not very experienced with client-side Linux, especially not with Arch-based systems, but I was wondering a bit, why in xinput the devices seem to use wayland driver, but for libinput -list-devices the pointer/touchpad seems to be a Synaptics device (see first post). Don’t know if that’s relevant at all, but somehow feels this could be conflicting…

Output of xinput list:

Edit: I just tried the libinput debug-gui tool and surprisingly there (and only there) the touchpad behaves as expected :face_with_monocle:
