Thinkpad - Trackpoint configuration on 18.10+?

Question

I have a new Lenovo x280 and am trying to configure the trackpoint following tips that worked on older machines/installs.

However, the command:

find /sys/devices/platform/i8042 -name name | xargs grep -Fl TrackPoint | sed 's/\/input\/input[0-9]*\/name$//'

returns nothing, the only device I can find is the keyboard.

Has something changed in 18.10 or do I need to do something else to configure the trackpoint properly?

Answer 1

I had the same problem in Ubuntu 19.10 on my T480. I was able to find the files in /sys/devices/rmi4-00/rmi4-00.fn03/serio2.
