I just installed the new 2.6.16 kernel and xorg-x11-drv-nvidia-1.0.8178-7.lvn5 kmod-nvidia-1.0.8178-6.2.6.16_1.2080_FC5 all seems to work fine except if i try to run glxgears : Xlib: extension "GLX" missing on display ":0.0". Error: couldn't get an RGB, Double-buffered visual what's the problem ? I have to enable something manually ? Thanks Eric
