I play BeatSaber and few more VR games using ALVR and it's working great. (But I know that not all VR games fully work on Linux)

But you just need to know that its for Quest headsets running mostly over Wi-Fi (but you can also run over USB) so your milage may vary depending on your WiFi setup.

I use Arch btw 😅

If the only issue you would've had is the audio not working, and your chosen distro uses PipeWire, yes. Otherwise I'm not sure, it's one of the reasons I haven't switched on my desktop.

It was viable before. I used it for a bit to play no man's sky

It is already viable, have a look at lvra.gitlab.io for information about what works and what does not. I've tried to use ALVR before but eventually switched to wivrn since I found it to be more reliable, probably since it does not rely on SteamVR.

I wasn't going to get vr until it was plug and play on Linux and that has been the case for me so far, using alvr

I guess the best equivalent to Virtual Desktop for Linux?
