For instance, you'll have DRI2 in all sessions. Hmmm, as said I had this excessive X.org CPU usage with 6.12.192 and EXA enabled. But then, this was with some 2.6.32 and without KMS. Maybe that CPU usage problem doesn't happen with 2.6.33 and KMS. Is Debian squeeze/sid/experimental ready for KMS with Radeon? Or do I need to recompile some packages with different settings? http://wiki.debian.org/KernelModesetting does not yet mention Radeon. If installable packages are ready for it, I think I will compile a 2.6.33 with KMS, try it and add to the wiki if it works ;). -- Martin 'Helios' Steigerwald - http://www.Lichtvoll.de GPG: 03B0 0D6C 0040 0710 4AFA B82F 991B EAAC A599 84C7
