<pre>The trackpoint on the X280 is too fast. I first thought that adding an entry to
the systemd hwdb is correct, but changing the acceleration to 64 there improves
things only until libinput also reads the property.
<a href="https://github.com/systemd/systemd/pull/8442">https://github.com/systemd/systemd/pull/8442</a> has the relevant matching rules
for the machine.
The libinput-measure-trackpoint-range utility seems to suggest a value of 70
for the machine. Though, to be honest, it is hard to tell how much one is
supposed to press. Doesn't feel perfect, but I am not a big trackpoint user, so
might be misinterpreting things.
Rule:
libinput:name:*ALPS TrackPoint*:svnLENOVO:*:pvrThinkPadX280:*
LIBINPUT_ATTR_TRACKPOINT_RANGE=70</pre>
