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.
(Read this in capslock) How did you get the Xbox controller firmware to work?
Seriously! I tried it for a whole afternoon, before I gave up and just bought a generic gamepad.
This was the last time I bought a Microsoft hardware thing. Fuck u MS!
I believe the only way to firmware up an Xbox controller is on an Xbox or through the Xbox Accessories app on Windows. I've been using my work laptop to update my Xbox controllers.
As an alternative, some of the 8bitdo controllers are in LVFS, and I've heard the PlayStation Controller Firmware Updater works in WINE for DualShock and DualSense controllers.
I cheeted, I used my partners Win11 desktop, installed the XBox accessorys app, update completed in about 4 minutes.
I have had success with windows based firmware update tools using wine in the past; with a lot of troubleahooting. Her PC is 2 meters from me and it was done in 4 mintes.... Yes I feel dirty, but it's a one-off firmware update. Pick your battles.
