The line between a Linux user and a Linux power user is a bit gray, and a bit wide. Most people who install Linux already have more computer literacy than average, and the platform has long encouraged experimentation and construction in a way macOS and Windows generally aren’t designed for. Traditional Linux distributions often ask more of their users as well, requiring at least a passing familiarity with the terminal and the operating system’s internals especially once something inevitably breaks.
In recent years, however, a different design philosophy has been gaining ground. Immutable Linux distributions like Fedora Silverblue, openSUSE MicroOS, and NixOS dramatically reduce the chances an installation behaves erratically by making direct changes to the underlying system either impossible or irrelevant.
SteamOS fits squarely into this category as well. While it’s best known for its console-like gaming mode it also includes a fully featured Linux desktop, which is a major part of its appeal and the reason I bought a Steam Deck in the first place. For someone coming from Windows or macOS, this desktop provides a familiar, fully functional environment: web browsing, media playback, and other basic tools all work out of the box.
As a Linux power user encountering an immutable desktop for the first time, though, that desktop mode wasn’t quite what I expected. It handles these everyday tasks exceptionally well, but performing the home sysadmin chores that are second nature to me on a Debian system takes a very different mindset and a bit of effort.
You just described Bazzite. You can literally install the KDE version, same as you’d find on a Deck, and get right to gaming. No tinkering required. Steam is installed by default, Bluetooth works as expected, USB controllers work when plugged in.
The only time you might “tinker” with gaming is when you want to install, say, an emulator or Heroic from the Discovery store (flatpak) to play your non-Steam games, all of which is optional.
SteamOS isn’t going to offer significant benefit, except it might get Valve-specific fixes before they upstream the patches. If you’re waiting around, expecting SteamOS to be some shift in the distro landscape, I think you’re going to be disappointed.
Playing games from outside Steam is less tinkering in Bazzite than SteamOS because Bazzite supports those out of the box. I don’t have a Bazzite install in front of me right now but IIRC it comes with Lutris preinstalled. On SteamOS that’s an additional installation step.
It’s been a hot minute since I installed Bazzite, but it might even come with Heroic preinstalled. I think it did come with Lutris by default, as you say.
Can confirm, ships with Lutris.
