Bug description:
  Touchscreen is unresponsive on fresh 13.04 Ubuntu installation.  All
  other devices work.

  Touchscreen shows as working and 'states' are correct for any xinput
  --list off of a cold boot.

  However, if I (at any point) "Suspend" the system, then awaken it, the
  Touchscreen immediately functions properly.
