Sure, but that’s kinda the point, isn’t it?
Linux has so many possible splintered ways that systems could be configured that it’s hard to support, especially when a Steam Deck native could then be adjusted to work by your userbase, without any support or testing required.
Still a win, and fair that Larian doesn’t have the budget for a full Linux release.
Maybe try ReviOS? It’s a “playbook” file you run on a clean Windows 11 install that strips out all of the telemetry and junk, and mostly “just works”. The only big potential pain point, imho, is not getting automatic driver updates from Windows Update.
I just installed CachyOS with virt-manager running ReviOS in a virtual machine. For my needs, it’s amazing. Arch Linux allows for easy updates to the latest versions of software and CachyOS further improves it with optimized, pre-compiled packages, which is particularly relevant for a smooth gaming experience. (Outdated packages aren’t a good mix with new games, and the optimized packages improve performance.)
The only “big” challenge I’ve had with Windows is getting videoconferencing working smoothly (my webcam is flickery), but that’s not a big deal. Zoom in Linux works great, and Teams/Zoom both work well in browser (in Linux). So, most of my work stuff is in the VM, but I have Zoom and a separate browser (for Teams meetings) installed in Linux.
This setup requires a bit of technical skill; you need to be able to find and follow guides. (Ex. I needed to troubleshoot why I couldn’t change the VM resolution, and the fix was to download a set of VM tools in Windows.) If you have light technical skills to search for and read guides, it shouldn’t be too challenging.
(I use Arch, by the way.)
