Hi I have a Dell Inspiron 9400 with a GeForce 7900GS. The FC6 test4 (pre-release) is full update on Oct 12. Kernel is 2.6.18.1-2759 and GeForce driver v1.0.9625 from NVidia. I can't start AIGLX Desktop effects. Instead I got "Desktop effects could not be enabled". Any idea? Thanks in advance Laurent
