Trackpoint moves on its own.

Suddenly the track point starts moving on its own. I don't have a drift time value. This is what I got with the command

sudo udevadm info --attribute-walk /dev/input/event23

Laptop model: Thinkpad T14s gen 3

Re: Trackpoint moves on its own.

This happens sometimes
Try to remove the red nipple and clean it up and its socket.

You can also watch the event generated by:

libinput  debug-events /dev/input/event9

If you feel it too sensitive you can also change the value:

echo 50 | sudo tee /sys/devices/platform/i8042/serio1/sensitivity

Re: Trackpoint moves on its own.

The frustration of all thinkpad owners: over-sensitive red nipples.

I've had this only very rarely on my T450, but it seems - on this machine - to be triggered by sleeping or waking from suspend with some pressure on the trackpoint.  I gather the pressure upon waking is calibrated to "zero" and if that is removed there's then a drift.  Cycling back to sleep and wake again has consistently resolved this on this machine.  Though I also have X200s that tend to be more prone to seemingly random drift.
