The announcement sparked my curiosity about the operating system behind the Steam Deck. While many recognize SteamOS as a Debian-based project, SteamOS 3.0 is described as "Arch-based." I'm new to Linux and understand the general differences between Debian and Arch, but I'm still learning how important this change is. So far, few have discussed it much. Would anyone like to share insights on what this means for Linux gaming, especially with the strong pre-orders already in place?
Searching online reveals a statement from the Arch Wiki that probably explains the situation. Based on general understanding, it seems this advanced SoC might be running an outdated kernel and libraries, making Debian stable a better choice since it offers newer software updates without being unstable. From my experience transitioning from Windows to Linux, KDE is the closest alternative to Windows without fully replicating it. Over the past decade or so, I've experimented with other options, but KDE consistently stands out as the most user-friendly.
It motivates developers to focus on targeting a specific proton that isn't a built-in feature and should be avoided whenever feasible. Although it may increase game availability on Linux, it's not the direction I prefer for developers. However, if you examine game code and understand how Linux packaging functions, you'll realize a genuine native port isn't the best choice.
Some Linux game versions seem to perform better when using Proton instead of running them natively, which might make developers focus more on optimizing for it rather than creating original native titles.
They picked Arch for its light weight, solid reliability, and fast updates. For the desktop environment, they went with KDE Plasma because it resembles Windows, looks appealing, uses fewer resources than GNOME, and feels more refined than simpler options like XFCE.
I've tried Debian, now I'm leaning toward other distros like Manjaro for gaming or Ubuntu for work. I've spent quite a bit of time with Arch in the past, but lately I prefer someone else to manage the tweaks. My take – not everyone agrees – is that Debian isn't as reliable as it seems, especially when you need the latest updates. Arch's continuous release model lets you adopt new features like Vulkan quickly; Debian usually requires waiting a year or using a PPA for timely support. For gamers, this matters because a fresh update can mean noticeable changes in performance or even game compatibility. Valve handles it well with regular patches, but if you're looking for native titles, a more current setup is worth the effort. The whole scene is moving fast compared to Windows, so staying ahead is crucial.
I also attempted to install Debian once, but it caused a lot of concern during the setup.
Wouldn't be surprising if you're considering different distributions. Debian stable is currently at version 4.19. Your setup includes a 5900x desktop and a 4800U laptop—desktop might work but hasn't been tested yet. The APU doesn't seem to support it, as drivers were added in 5.8. You could try Debian testing for an updated experience or move to Arch with the latest stable kernel. Edit: your U model is actually 4700U, not 4800U.
