<pre>On #wayland irc channel I got the instructions to run:
# libinput measure trackpoint-range
This tool measures the commonly used pressure range of the
trackpoint. Push the trackpoint:
- Four times around the screen edges
- From the top left to the bottom right and back, twice
- From the top right to the bottom left and back, twice
A minimum of 1000 events for each axis is required
Movements should emulate fast pointer movement on the screen
but not use excessive pressure that would not be used
during day-to-day movement. For best results, run this tool
several times to get an idea of the common range.
Trackpoint sends: max x: 52, max y: 49 samples [6968, 6780]^C
