Use a different version of NVidia Driver
Here is my current setup:
Video card: nVidia Corporation NV41 [Quadro FX 3450/4000 SDI] (rev a2)
Video Card Driver: akmod-nvidia.i686 180.25-1.fc10
I am having some weird problems though (Screen turns black when I quit an openGL program). Is there a way to use a different version of the driver to see if that helps?
