Yeah, I didn't know those requirements were a thing until a few hours ago. I've been running Steam on KDE Neon with Intel embedded graphics and everything is great out of the box or easily installed. I just had a feeling that there would be "SteamOS but with Nvidia" thingy for Ubuntu, Arch and Fedora that has some nice features.
I mean, Linux gaming is moving so fast it's hard to keep up. I wouldn't be surprised if in 2025 we'll have a distro that has "run as game server" and "use Steam" toggles in the installer and you can access it from an Android TV from first boot.
