Nvidia Drivers on Fedora Core 5

First install the atrpms repository (in this article)

yum install nvidia-graphics

All the dependencies should install as well

next edit your device in your /etc/X11/xorg.conf

Now we must configure our xorg.conf file to use the new driver. First, always make a backup of the default xorg.conf. As a su, type:
$ cp /etc/X11/xorg.conf /etc/X11/xorg.default

Open xorg.conf for editing:
$ vi /etc/X11/xorg.conf

Locate Driver "nv" and replace with Driver “nvidia"
Add the line:
Load "glx" # 3D layer
in the same section that contains Load "dbe".

Look for any lines that read Load "dri" or Load "Glcore" and remove them.

Start the X server by typing startx. You will see an Nvidia splash screen if you are successful. If you run into trouble, you can restore your old xorg.conf by typing:
$ cp /etc/X11/xorg.default /etc/X11/xorg.conf

When you have your driver successfully installed, newer versions in the future can be installed using:
$ yum update nvidia-graphics
