SatyrSackSteamOS has been out on Steam Deck for 18 months, but still no general release in sight. I wouldn’t hold my breath. I think we’ll just have to continue to make do with the likes of ChimeraOS/Nobara.
BananaTrifleViolinTrue. There is an unofficial release - HoloIso - which uses Valves packages but is not quite complete. Also manufacturers may be able to get access as Valve previously has been keen on getting other manufacturers to buy into it's hardware attempts (e.g. Steam PCs previously, and VR now) but I'd expect the manufacturers to be making a big deal of it if they were launching a SteamOS handheld. It seems Valve want to keep exclusivity on Steam Deck for now (which makes some sense given how successful it's been)
(which makes some sense given how successful it’s been)
It really doesn’t make sense, considering how small the profit margins probably are, if any.
What would make sense is making the Steam-first OS open to be installed on any device.
Is there some specific feature that SteamOS brings to the table that people are looking for? So far as I know, a stripped down installation Debian or Ubuntu (Valve likes to base their packages off of Ubuntu) with an Xserver scripts that directly launches steam in big picture mode ought to create roundabout the same experience I would think.
HyperHyperVisorSteamOS 2.x was based on debian, but that hasn't been updated in years. The Steam Deck launched with SteamOS 3, which is actually built on top of arch and is much more akin to Manjaro. As for your question, it's mostly the "game mode", which uses IIRC Wayland and wraps games inside gamescope which provides a bit more control in the form of controlling frame rate, resolution, etc externally, but regardless, that can and has been achieved in custom distros. I think the main appeal of SteamOS honestly is the package of an immutable OS optimized for running games on steam. It prevents non-linux users from breaking things and tries to make it feel more like a "console" with a "desktop mode" (KDE Plasma) and "app store" (ala flatpaks). I've toyed with the idea of running it or similar on my gaming PC but always run into the difficulty of Nvidia drivers on Linux.
I had no idea they switched distros. Or ran Wayland for that matter! Truly it's the future. But that's a good point, being able to say on the "box" that is specifically runs SteamOS certainly brings about a level of consumer and investor assurance.
As far as the nvidia drivers go. Only advice I can offer is that I've never had any sort of auto install, package based install, or any sidestepping of the default installation of the driver work for me. It's always borked. The only reliable method I've found is the old school drop into the line terminal, shutdown all GUI, and running the nvidia provided install script (which sucks, I know).
Yeah, I've gotten Nvidia drivers working, but always with issues in performance or things like Wayland not working and I eventually decide "that was fun to play around with, back to Windows". Specifically the whole immutable OS thing for me is nice too. Linux is my OS of choice for development work, but it's so easy to screw things up when trying to make games work nicely and my ideal "it just works" gaming machine can ignore the OS entirely (looking at you, Windows random forced reboots or virus scans), so having big single updates rather than individual packages and no risk of trying to get WINE etc up and running breaking something with the OS is nice. Not to mention, it's much harder for a small child to brick it than a normal Linux distro or even Windows for that matter. Fedora Kinonite is on my radar for a future distro because of this, I just haven't decided if I prefer the Fedora ecosystem over Ubuntu or Manjaro.
I honestly think it’s just because most people have nvidia and steam on linux and nvidia don’t work well together and linux and nvidia and just nvidia in general. It works enough but is not a smooth experience. Maybe once the open source drivers are fleshed out more it’ll be better
