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:

Key components:
- Linux Kernel 5.12.12
- Mesa 21.1.3
- NVIDIA 465.31
- steamos-compositor-plus 1.8.3
- Steam Buddy 0.11.2

Changelog:
- Rename to ChimeraOS
- Updated installer with wifi support
- Added basic MangoHud configuration support via Steam Buddy
- Added racing wheel support
- Fixed bluetooth pairing through the Steam UI
- Fixed high CPU usage when MS Xbox controller dongle is plugged in
- Added Mr. Rescue, Sonic 3: Angel Island Revisited, Cave Story NX to Flathub
- Added Proton 6.8 GE-2, 6.9 GE-2, 6.10 GE-1
- Added media key support
- Improvements to updater reliability
- Improved reliability when starting flatpak/flathub apps
- Restore default steam play settings for a game when user override is removed
- Merged Steam Tweaks into Steam Buddy

You can download it from the official website.

Woah, this is totally awesome! I've been meaning to check out GamerOS for a while now (guess I'll be checking out ChimeraOS now haha)
You mentioned that the Steam Buddy tool helps to install GOG games and all of that, but what about those Windows-only GOG games that need special tweaks (the older ones, the kind you really can only easily install-and-play using Lutris with its custom install scripts)? It would be great to have out-of-the-box capability for such games.

Quoting: denyasisThere are real Chimeras. Not fantastical at all. It's just... They're plants. There might be others but that's all I can remember from school 20 years ago.
Not just plants. It's an organism that contains more than one distinct genotype (the set of genetic material). Most marmosets are chimeras.

I did a take, went and looked it up . . . man, marmosets are weird.

Quoting: slaapliedjeI like the name, though I don't think it fits for what is essentially Steam on top of Arch. StarchOS. 😜
Chimera uses an update mechanism called frzr, which delivers pre-built read-only systems images. It happens right now to be Arch based, but it can be switched to any other OS if needed.
Is very likely that Arch will be used for the foreseeable future, but the relation between Chimera and its underlying OS is not fixed.

Very cool. I didn't know it existed in the animal kingdom.

It happens in people, too. It comes up every now and then with questions of maternity, organ donation, and things like that, or if there's mosaic skin colouration or differently-coloured eyes. Otherwise no one notices. It's become more common since the invention of fertility treatment, since you're then more likely to be carrying more than one embryo.

Can make a personal confirmation to that. Double DNA club. Does sadly not make me able to breathe fire.

There is a really cool group of cartilagenous fish (related to stingrays and sharks) that are also called chimaeras:
https://en.m.wikipedia.org/wiki/Chimaera

I don't really get why the old name was so disliked, but it's ok, names apart it's great that this distro is alive and well.

It occupies a very special niche and does so much better than SteamOS.
Quoting: DerpFoxI way prefer GamerOS over ChimeraOS at least you know what the target is.
I understand GamerOS is not perfect, but the new one doesn't make any sense at all.

Oh I know! Imagine coming up with a name that shows this version has the DNA of two different distributions and is combined into a single usable platform! How awesome would that be! It'd also be just like what a Chimera is!!! Oh wait! Maybe they did think this out and people are just ignorant...

The only ignorant thing is assuming that having to know the entire backstory of a distribution in order to understand the name is a good idea.

Names are used to attract new people, not reaffirm existing ones. It is an advertisement of sorts and should be chosen with that in mind.
Once you're already "in", the name becomes kinda irrelevant as long as it isn't totally terrible. I use Manjaro - but at this point I couldn't care less if they changed the name to Everest.
