From the README:
Q: When I start X it fails and my XFree86 log file contains:
(II) LoadModule: "nvidia"
(II) Loading /usr/X11R6/lib/modules/drivers/nvidia_drv.o
No symbols found in this module
(EE) Failed to load /usr/X11R6/lib/modules/drivers/nvidia_drv.o
(II) UnloadModule: "nvidia"
(EE) Failed to load module "nvidia" (loader failed, 256)
(EE) No drivers available.
A: The nvidia_drv.o X driver has been stripped of needed symbols;
some versions of rpm (wrongly) strip object files while installing.
You should probably upgrade your version of rpm. Or, you can install
the NVIDIA_GLX package from tar file.
Does this help?
