Re: Have to reinstall drivers each logon for FC6.
I had the same problem with Debian. I figured out that the problem was the nvidia-glx script debian ran every time it booted. When I disabled the driver installation worked well.
Look for nvidia-glx or linux-restricted-drivers under /lib/ directory.. ubuntu have a directory named linux-restricted-driver that contained a nvidia driver, you need to delete it and install the drivers from nvidia if it exist on your system.
