compiz on ATI dual-head, Jaunty

[synexo]

I've been unsuccessful after trying most all advise I can find on getting Compiz to work on Jaunty 9.04, with the ATI driver and dual-head running. When trying to enable effects, I get "The Composite extension is not available". Here is some additional info:
