ok dude i have a better solution: this works for all linux distros.
download the latest nvidia file from www.nvidia.com
(i think it is 5336)
i think the name is: NVIDIA-Linux-x86-1.0-5336-pkg1.run
then go to console by pressing Alt+Ctrl+F1
login as root
then type: init 3
now go to where u d'loaded the package, (i mean change directory using the cd command)
then type: sh NVIDIA-Linux-x86-1.0-5336-pkg1.run
follow the instructions.
after the driver is installed, run "switch2nvidia"
