Trackpoint deceleration is not working on Ubuntu 16.04 , 17.04 on Dell latitude 5470

I am unable to achieve acceptable results with all the different knobs that are available. If I tune down acceleration, I am able to do detailed pointing, but the stick is generally so slow, that it takes ages to cross the screen. On the other hand, if I increase the acceleration, even the slightest movement of the stick makes it jump significantly on the screen so that I am unable to do detailed selections.

The trackpoint actually works on Windows, so this is not hardware related bug. This is linux related, because guy with fedora has the exact same behavior as I have. Pleases help
