It is mostly working fine these days. I don't think that will be a show stopper for a new standalone HMD from Valve.

I mean, it is patchy but there. NVidia is a problem, like always. My friend struggles with the Index because of the shitty NVidia DRM drivers causing reprojection issues.

I’m on a Quest 3, and getting things to work wirelessly with WiVRn was basically plug and play, in the figurative sense. Install WiVRn server and client app, add launch arguments to whatever you’re trying to run in VR and you’re set. It’s more reliable than Virtual Desktop with SteamVR on Windows, in my experience.

That said though, getting FBT working was a little fiddly, requiring patched versions of xrizer and WiVRn, then making sure both of those can write to the proper devices. Once that was done though, it just worked.

Valve has mostly neglected SteamVR on Linux. There's Monado and associated projects that are much better performance wise but are still ironing out integration of equivalent features. it's a playable experience, and in some cases can drastically improve FPS but it's not a drop in upgrade. If Valve wants to improve SteamVR they would do well to adopt a similar approach to what they've done with Proton and put resources towards the open source project and use it as a base for a SteamVR 3.0.

My Index worked great on AMD hardware, linux software, to play HL Alyx.

At the time, I was using PopOS!, and the straight .deb version of Steam/Proton, mesa drivers for AMD.

Only thing that stuck out was initially that it wasn't properly registering the front pass thru camera properly as its own video source, but that got fixed... well, literally years ago now.

I never got my OG Vive to work smoothly in Linux so it's the last thing I've kept a Windows dual boot for. Would be nice if I could get rid of it when I upgrade headset, which I've also been reluctant to do due to uncertain Linux support.

It's a mess in Windows, I'm not even touching it on bazzite.

Yeah, I was about to say that I'd buy the shit out of that headset, but after valve fixes VR on linux.
I had it not to great, but it usable after I switched to linux couple years ago on gtx1070, but since switching to AMD card I didn't manage to get it working. No Wayland support also sucks, I don't want to swap to X every time I want to run VR :(

They have done great stuff with Wine/Proton but valve can't even get Steam itself working that well on Linux. I have almost constant UI rendering issues.
