Same problem with i7 - intel 4770 processor desktop (internal 4770 graphics only but using 3 screens connected) with Ubuntu 14.04 - after 1hr inactivity, computer is set to suspend. On starting up again by pressing a key or moving mouse, the poewr button comes on constantly (rather than flashing), the keyboard caplock/numlock keys work etc., the monitors wake up but display nothing.
