[Doug Gray <doug2233@xxxxxxxxx>]

I can reproduce this problem by logging out and logging in with the external screen attached.  Compiz chokes the computer running at around 150% CPU usage alone.  
If I unplug the external screen the laptop seems to get largely back to normal.
Then plugging the screen back in - the situation is as I previously noted, compiz usage is high but not so bad.
Rebooting or logging out then back in triggers the very high compiz usage.
