Public bug reported:
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.
With Ubuntu 16.04 at least on the t450s everything worked well.
