i have the same problem with FC 6.
I have a NVIDIA GeForce 6400 Go.
@Zander: I done install steps in your link.
what i wonder about is when i execute command " gcc -v " , it says:
Using built-in specs.
gcc version 4.1.1 20070105 (Red Hat 4.1.1-51)
Maybe itś a Problem because FC6 has i686 Architecture.
Linux noname 2.6.19-1.2895.fc6 #1 SMP Wed Jan 10 18:32:37 EST 2007 i686 i686 i386 GNU/Linux
Also i tried to Install via Yum(Extend).But i get this Error:
thank you in advance for any help.
