Comment 58 for bug 1746740

Not 100% certain if this is the right bug for this, but I'm seeing similar behaviour for trackpoints and touchpads on the Thinkpad X230 and Thinkpad X131e for at least Ubuntu (standard) and Ubuntu MATE.

Laggy is a vague term, but for me specifically I'm seeing that the cursor moves in a constant motion until I stop. Then after a small moment, it "jumps" a short/random distance in the direction of motion before I stopped. This is very very pronounced when using the trackpoint.

I see some similar reports on various corners on the internet that is similar to what I'm seeing:

  - OP reports "The cursor moves slowly but suddenly very fast."
