I have been running Bazzite on my TV for a few weeks. Was using PopOs however I was having issues with some games not launching, probably to do with the combination of Unraid VM, GPU passthrough, Xorg with fractional scaling on a 4k pannel. Bazzite with “Game mode” is amazing. Closest thing to Steam OS that I know about. Everything just worked with the exception of needing to firmware update my xbox controller to get it to work. Game mode seems to report as a steam deck.
Have you tried xone?
I’m on Bazzite, and AFAIK all drivers are already pre-installed.
I already tried using a VM with passthrough, but it didn’t work. I’ll try using my brothers’ Windows PC next.
Xone is indeed pre-installed, Xbox controllers are just plug and play, or pair and play for Bluetooth. You need to open a help thread if you’re having issues, but try updating the firmware of your controller in the meantime.
