Background
I installed Arch Linux on ThinkPad X1 Carbon 2018.
I edited /sys/devices/platform/i8042/serio1/
the file as well as ThinkPad x240 because I wanted to speed up TrackPoint.
But did not works…
Solution
Create the following file.
Path: /etc/libinput/local-overrides.quirks
Content:
[Trackpoint Override]
MatchUdevType=pointingstick
AttrTrackpointMultiplier=2.5
TrackPoint is a really good pointing device!
