SteamOS is a fork (modified version) of a Linux distribution (distro) built by Valve for its Steam Deck handheld, previously based on Debian but switching to Arch Linux when the portable device launched in 2022. Its UI is practically identical to Steam's "Big Picture" mode, designed initially to simplify PC gaming on large-screen televisions, but it can switch to a traditional desktop UI based on KDE Plasma.
However, it's now optimized for various screen sizes and focuses on supporting controller inputs rather than a traditional mouse and keyboard. While SteamOS is still primarily built for AMD hardware, starting with the Steam Deck and recently expanding to the Lenovo Legion Go S, it can be compatible with NVIDIA and Intel Arc graphics with mixed success.
