You might want to print out these directions:

1. Hit "CTRL ALT F2" for a command line.
2. Login as root or do "su -"
3. Run: "init 3"
4. Run: "sh <nvidia-installer-filename>.run"
5. Once installed, edit /etc/X11/xorg.conf:

In section "Module," add the line (if it's not there already):
	Load "glx"
Comment out the lines in the same section (if they exist):
	Load "dri"
	Load "GLcore" <--this one probably won't be there

In section "Device," change:
	Driver "nv"
To:
	Driver "nvidia"

6. Run: "modprobe nvidia"
7. Run: "cp -a /dev/nvidia* /etc/udev/devices"
8. Run: "chown root.root /etc/udev/devices/nvidia*"
9. Run to restart X: "init 5" or restart the machine.
