            Bug ID: 106448
           Summary: Trackpoint reacts jumpy and isn't precise when moved a
                    short distance
           Product: Wayland
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: libinput
          Assignee: wayland-bugs at lists.freedesktop.org
          Reporter: rosgnilk at gmx.ch

I made a fresh install of Ubuntu 18.04 on a thinkPad t450s and t480s. The
trackpoint reacts, especially if i want to move it only a small distance, very
jumpy and erratic.
It is very difficult to hit a precise spot on the screen because if I press
with very littel pressure the cursor doesn't move and with a little more it
makes a big jump. Somethimes it moves backwards first and then makes a jump in
the intended direction. To summ up the trackpoint is very difficult to handle
and changing the speedsettings doesn't change the issue.

After posting the bug under
https://bugs.launchpad.net/ubuntu/+source/libinput/+bug/1769322 I've installed
the newest version of libinput-bin "libinput-bin_1.10.6-1_amd64.deb" and the
behavior did inprove but it does still not work flawlessly. The cursor still
jumps somethimes especially if moved a short distance.

With Ubuntu 16.04 at least on the t450s everything worked well.
