When I go to a single monitor desktop effects work correctly. This was working before the upgrade to JJ 9.04. Please advise what I need to do to enable compositing.

That makes complete sense. I will know if that fixes it, Monday when I make it in to the office and dual monitor setup.

You're talking about "separate x screens"?
