--- Comment #4 from Peter Hutterer <peter.hutterer at who-t.net> ---
see https://cgit.freedesktop.org/wayland/libinput/tree/src/libinput-util.h#n57,
default range is 20. so if your range is miles off from that, it'd explain the
issues.

> Maybe 'measure trackpoint-range' could just print the current value

I'd rather not, there's little benefit beyond possibly introducing a bias.

> It would also be useful if it printed which /sys/class/input/eventN node it was using

Your wish, my command, etc.

I've done this too many times to be able to write an to-understand summary
here. I was hoping the example compared to a dmi modalias on your system would
be sufficient to guess the rest. Any chance you can write a blurb for me here?
Send it directly to me please (to my bugzilla email), thanks
