Kind of a wild shot-in-the-dark, but when the screen goes away because
of the screen saver/lock, can you switch to a virtual terminal?
(ctrl-alt-F1, etc.) And when you switch back to the virtual screen
that has the X11 session in it (ctrl-alt-F7, 6, or 8, maybe), does
that help it re-recognize the monitor?

Also, have you tried ssh-ing in to an admin account and using sudo or
su to kill the desktop manager or login session?
