What is sgfxi?
sgfxi is a self-updating nvidia, ati/amd fglrx, and xorg free driver installer and xorg configuration script written for originally for Debian, but since expanded to also include support for Ubuntu and Arch Linux systems.
Easy to use, updated usually the same day as new nVidia drivers are released. fglrx support is much less reliable because ATI/AMD does not actively support cutting edge software, but it should be good for most fixed pool distributions based on Debian/Ubuntu, and the Debian Stable/Testing/Sid branch, as well as Arches rolling release model.
This project includes the patches used to keep up with latest kernels, and sgfxi includes an automated patch installer as well.
