once you get the blank screen, does ctrl-alt-F7, ctrl-alt-F8, ctrl- alt-F9, ctrl-alt-F10, ... get you back to a graphics console? does ctrl- alt-F1 through F6 get you to a text login console where you can restart the gdm service as root?
I often see that on our multi-user systems upon user logout; also I've wondered if it had to do with VNC servers coming and going in the background.
