Dubbed Alchemist, SteamOS is an Open Source Linux distribution based on the Debian GNU/Linux 7.1 (Wheezy) operating system. It includes a backported eglibc 2.17, a variant of the GNU C Library for embedded systems, from Debian Testing. Being powered by Linux kernel 3.10 (3.10.11), SteamOS includes several third-party graphics drivers that mostly support Nvidia graphics cards, as support for AMD and Intel graphics is still experimental.
