Next time this happens, try telnetting in (or ssh or whatever).  I used
to have similar problems with Matrox cards (not on Dual Head, though)
and I found that I could still login remotely.  Then I could restart the
machine cleanly (killing X didn't help).

I've had enough problems with Matrox cards under Linux that I just avoid
the combination.

I see a mouse.  Where?  There, on the stair.  And its clumsy wooden
footwear makes it easy to trap and kill.  -- Harry Hill
