I have mirroring working on my iBook G4 with a Radeon 9200. Xorg 6.8.2 does not include the necessary code for this, so there are two things you can try: 1) Try Xorg HEAD. 2) See what patches Ubuntu uses in their Xorg package. They have backported some of Ben's work from HEAD, and so their Xorg (6.8.2-10) can do mirroring at least on my iBook. cheers, John
