I installed my fglrx drivers (catalyst 8.6) and fglrx confirmes that it should work.
Direct rendering ist working, too.display: :0.0 screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: ATI MOBILITY RADEON X600
OpenGL version string: 2.1.7659 Release
Desktop Effects work quite well.
But if I start an OpenGL Game (like Spring), I get the message mentioned in the topic.
What could be wrong and what could I do?
I should add, that I upgraded from 7.10 before. Perhaps the xorg.conf is corrupted?
Thanks a lot in advance!
