Getting a console-like big-screen experience with Linux gaming was a thing with SteamOS until Valve stopped updating it, then came along GamerOS to carry the torch which has evolved again with a new name of ChimeraOS.
ChimeraOS has the same idea just a fancy rebranding, to remove the terrible GamerOS naming. Nice. It also now has an actual website that's a bit more fancy.
For those not aware of what it actually does: it gives you an experience that boots directly into Steam Big Picture, powered by Linux, for an improved couch-gaming setup. However, it's a lot more than that. It has a built-in web app to manage installing non-Steam games known as "Steam Buddy", enabling you to run games from GOG, emulators and many more services.
Here's all the main changes for what's now ChimeraOS 25:
- Linux Kernel 5.12.12
