When i run this test on a normal machine, the change of coordinate is
very small and smooth:

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  CID: 201301-12655 Lenovo X230S

  Steps:
  1. Install 12.04.3 and boot to desktop.
  2. Try to control coursor with the trackpoint (TPPS/2 IBM Trackpoint)

  Expected result:
  Cursor could be controlled smoothly by using the trackpoint.

  Actual result:
  Cursor jumping around, if try to move it vertically / horizontally, it will move toward that direction and jumping in a zig-zag pattern. 

  Please find attachment for xinput list-props, xev and evtest result.
