The second SteamOS 1.0 Beta ISO image has been released, coming with bug-fixes and updates. Among others, it comes with Mesa 10.0.1, the driver for Intel Graphics, a kernel patch with support for KMS, OpenGL 3.3, 3D pass-through support for VMware drivers, USB auto-mounting for the the Steam controller, text assistance when building kernel drivers at first boot and the audio has been enabled to be managed directly from the desktop.
Also, Valve and AMD need to fix the compatibility issue between SteamOS and the AMD Catalyst 13.12 proprietary drivers. Since SteamOS runs on Kernel 3.10.11 and the latest Catalyst drivers (AMD Catalyst 13.12) work only on Kernel 3.12, Valve’s gaming system does not have support for the latest AMD GPUs yet, but AMD is aware of this problem and should find a workaround soon.
The latest SteamOS ISO image can be dowloaded from here.
The story so far:
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 a week ago) 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.
It requires UEFI support, Intel or AMD 64-bit processor, 4GB or more memory, 500GB or larger disk and NVIDIA, AMD or Intel GPUs.
