The ThinkPad X1 Carbon 5th couldn’t use its TrackPoint under Linux at all. Plenty of people were discussing the problem, but nobody had actually fixed it. Then a while back, with the X280 and X1 Carbon 6th entering internal testing, the issue finally got some attention, and it got solved.

Two problems, roughly: Multi-monitor output when docked TrackPoint and middle-button scrolling I wrote up some quick fixes last time, but these are better.
