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.

Two users with similar 'inconsistent' behavior until we discovered that closing the lid (therefore, for that user, going into 'Suspend' mode) or a manual 'Suspend,' was resolving the issue.
