Jon Vaughan (jsvaughan) wrote : Thinkpad t440s touchpad / trackpoint periodically stop working

Every 15 minutes or so, the cursor stops reacting to input from the touchpad or trackpoint. Unfortunately this machine has a "clickpad" instead of separate buttons and so it is impossible to use the machine without the touchpad, which means that Ubuntu is virtually unusable. In Windows on the same machine there is no problem.
