Re: More FC5 problems
I had a similar issue.
The NVIDIA installer was putting the modules in /usr/X11R6/lib, but xorg was looking for them in /usr/lib/xorg/modules
There's an installer option to specify where the modules should go, I can't remember it exactly, but run ./NVIDIA-Linux-x86-1.0-8756-pkg1.run.bin -A and it will list all the options.
Use /usr/lib/xorg/modules as the modules directory.
