TrackPoint on a X1 tablet not found at boot time, but working after physically reattaching the keyboard
The Trackpoint is not in the found at boot time and is not working. A simple sudo libinput list-devices does not show an entry of a Trackpoint. After removing the keyboard an reattaching it, the trackpoint is listed and working well:
