SteamOS is a linux distro based on Arch Linux, similar to any other. It’s a amalgamation of different pieces of software, including a traditional desktop environment (plasma). But it does not boot into the desktop mode by default, instead it boots into their own graphical environment (gamemode) by default, running their steam client.
That’s because their main focus is gaming machines, and that’s why they want gamers to be greeted with a consolized, 10-foot UI.
I think you’re confused because you think of steamOS being the UI (i.e. “Desktop Environment”) that welcomes you when you boot into it, instead steamOS is the entire package, including a “traditional” desktop environment (which is KDE Plasma), as well as their own (gamemode), etc.











it’s from the makers of “Heavy Rain” and “Beyond: Two souls”. The player has to play the role of three different humanoid androids throughout the game, and make choices that heavily affect the gameplay. Depending on the choices you make with every character, their story and outcome changes their future paths. It’s a good game, and can be bought quite cheap at sales. The acting is really good IMO.
