Comment 21 for bug 1439608

@Po-Hsu, can you try the following:

  (1) cat /proc/bus/input/devices to find the sysfs path of the clickpad node.
  (2) ls that node and check the event number of it
  (3) install evtest package and run `evtest /dev/input/eventX` X is the number from (2)

please post the result back here.
