The screen-saver you're previewing probably uses GL. Sounds like there is a chance you've not got DRI2 working properly? I've got a similar setup to you, and UXA is working nicely. (Just turn sync to vblank off in Compiz if you want framerate > 1/3 fps!) Check the Xorg.0.log to see if DRI2 is enabled. -- Peter Clifton Electrical Engineering Division, Engineering Department, University of Cambridge, 9, JJ Thomson Avenue, Cambridge CB3 0FA Tel: +44 (0)7729 980173 - (No signal in the lab!) _______________________________________________ xorg mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/xorg
