Title:
  [Dell Alienware 17 R3] FN+F11 Enable/Disable touchpad not working

Status in linux package in Ubuntu:
  Invalid
Status in systemd package in Ubuntu:
  New

Bug description:
  The touchpad does not work as expected. It can't be enabled or
  disabled through FN+F11 combination.

  The light (in the pad) always turns on, regardless of its non
  functionality.

  The problem seems related to bug #1523738, and some say solution #24
  (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1523738/comments/24)
  works, but it didn't for me.

  WORKAROUND: Executing the following via a terminal allows one to disable and enable the touchpad:
  xinput set-prop 13 "Device Enabled" 1
  xinput set-prop 13 "Device Enabled" 0

  But it only works if it is enabled from the beginning from the systems
  configuration GUI. If it is disabled, it doesn't do the expected
  behavior.
