Title:
  Touchpad suddenly not responding

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  After leaving my laptop on sleep mode for a while, then bringing it up
  again causes the touchpad to stop responding completely. Checked for
  it in the bus/input/devices folder and didn't see it.

  Laptop model: ASUS X450L
  Touchpad manufacturer: I presume to also be ASUS

  Symptom first appeared less than a week ago.

  EDIT: Forgot to mention, the touchpad comes back after a restart.
  Touchpad info is as follows:
