X hard locks when switching to console/shutting down.

[redgsturbo]

Often, when I'm shutting down my system, or switching from X to a console (as in ctrl-alt-F?) it hard hard locks X and I have to power cycle to get back up. Chipset is intel 945GM, and the system does this with compiz/emerald, or metacity *also*, this is sporadic behavior. It does it about 50% of the time

same problem here, when launch compiz i cant crtl alt f? and go back to the visual terminal
