The problems with GL I had was due to composition enabled in metacity (or in fact any composition - it's not metacity bug - kwin/compiz would do the same). The solution is KMS/DRI2, which for radeon just landed as highly experimental in kernel (and AFAIK are not released yet as drivers for xorg but will be soon). Here's starts the steps. In KMS-enabled system as many GTK+ apps redraw frequently there are many flushes to kernel. As a result it is unusable on xorg-server 1.6 on my, older, system. gnome-terminal cannot be scrolled and glxgears have 7-11 FPS instead of normal 200-220 FPS. I was advised to use xorg-server 1.7 if I'm 'feeling tester-like'. It was pointed out by someone that on KMS (s)he is using xfce-theme as more lightweight. As for sure KMS will improve before 2.6.32 I still feel that introducing OGL know is a bit too early. Hopefully it is just one kernel release too early. Regards
