Title:
  [Lenovo Thinkpad t440s] Touchpad periodically stops working

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  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. In syslog you see:
