The problem is not plugging/unplugging. It's when the notebook awakes from
suspension and finds the the projector situation changed. End-of-class is
normally hectic with student questions etc, and sometimes there's no time
for protocol.

And I would suggest that no program should crash under predictable 
circumstances. Is there no way Display can handle a signal on wakeup 
and check if the display situation has changed? I can imagine this problem
to appear if N monitors are connected and M (<> N) monitors after
an un-suspend. It doesn't seem so far-fetched.

PS: I am not criticising... just asking!
