Hello Linux Geeksters. Valve has recently updated their SteamOS, adding support for dual-booting and non-UEFI computers.
For now, the Ye Olde SteamOSe image is still better than Valve’s, since it has virtualization support and can run on computers with lower resources that the original SteamOS requires.
The story so far:
As you may know, Valve, now a member of The Linux Foundation, has initiated some ambitions projects: the SteamOS, a Linux operating system optimized for gaming, the Steam Machine, a gaming colsole that will run with SteamOS and the Steam Controller, a game controller specially designed for SteamOS and the Steam Machine. A demo video of the Steam Controller can be found here.
The first Beta version of SteamOS 1.0 (which has been released in November, 2013) is a customized Debian Wheezy system, running on Kernel 3.10.11, back-porting fresh Nvidia, Catalyst and Mesa binary drivers, uses SysVinit as the system’s default event manager, a personalized GNOME 3.4 as the default desktop environment for the Big Picture mode and Xcompmgr, a lightweight graphics compositor.
While the Nvidia graphics cards were supported by default, Valve has recently patched SteamOS to officially support both Intel and AMD GPUs.
