Failing to wake up from sleep? Try disabling your screen saver.

I've had this lockup issue several times now when waking from a long sleep (longer than 5 minutes). Other than that, everything is fine. I've waited several minutes (10-15) many times and my MBP will recover, so it's unclear what is going on (I haven't checked console messages yet). It appears to lockup the computer, but many times its just the screens. My sound and keyboard still work.

It's almost like letting it go back to sleep allows it to wake up properly, for lack of a more technical description.
