Trackpoint reacts jumpy and isn't precise when moved a short distance
Submitted by ros..@..gmx.ch
Assigned to Wayland bug list
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.
