[Krister <thekswenson@xxxxxxxxx>]

This can lead to an occasional complete melt-down on my system which
is manifested in one of two ways:
1) xorg goes into 100% CPU usage
2) compiz uses 100% CPU

Sometimes with the compiz variety, the system recovers somehow
although the windows are rearranged (does compiz restart?)

When I connect my machine to an external monitor all symptoms are magnified...
  the bigger the monitor the slower and the more likely to hang indefinitely.

Is there a command to restart compiz without logging out and restarting
X?
