            Bug ID: 105485
           Summary: Add hwdb entry for X280 trackpoint (too fast)
           Product: Wayland
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: libinput
          Assignee: wayland-bugs@lists.freedesktop.org
          Reporter: benja...@sipsolutions.net

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.

https://github.com/systemd/systemd/pull/8442 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
