If you ever struggled with the installation of the NVIDIA drivers on Linux (or Debian using this) then you should definitely check this out!

Really interesting, simple and useful script to install proper NVIDIA drivers on your Linux box.

Simply run:

cd /usr/local/bin && wget -Nc smxi.org/sgfxi && chmod +x sgfxi && sgfxi

as root user (or with sudo) and the script will automatically decide which version to install and will set up the xorg.conf file for you. It also works with other graphics cards manufacturers.
