ChimeraOS (originally GamerOS) is a big-screen Linux gaming experience designed for couch gaming (think like SteamOS) and there's a brand new release available.
While the current SteamOS is quite old and we're waiting on SteamOS 3 being released, this is the next best thing. In many ways it's a lot more than just booting into Steam Big Picture mode as it brings its own enhancements to work with other stores like Epic, GOG and more.
ChimeraOS 26 brings with it Linux Kernel 5.14.2, Mesa 21.2.1, NVIDIA 470.63.01, RetroArch 1.9.9 and other assorted system upgrades. On top of that it also renames Steam Buddy, the web-based tool for installing non-Steam software to Chimera. Additionally it adds a workaround for game windows not gaining focus with latest Steam client, adds support for 16:10 screen resolutions and gained the ability to push new Proton GE versions without a new ChimeraOS release.
There's also these bug fixes:
- fixed missing text in PSP games
- fixed GameCube games crashing with AMD GPUs
- fixed Epic Games Store login failure
- fixed regression with pairing Bluetooth devices
