For those who don’t know yet, 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 presenting the updated Steam Controller is available here.
If you want to try the SteamOS experience without installing Valve’s operating system, you can install the SteamOS session on your Ubuntu 14.04 Trusty Tahr or derivative system.
