There’s a lot of projects working to make VR on Linux a reality, although SteamVR technically works on linux it’s really only if you have a Vive/Index or third-party drivers. That, and SteamVR on Linux is a buggy mess anyway lol. I’m definitely not an expert in any of this though, I’m only just now going into college to pursue this stuff further lmao. Here’s some projects I’ve been following if you wanna look further:

• Monado, an OpenXR runtime built to run on Linux natively, and it provides features like finger tracking using the cameras on an Index along with other headsets
• V-Sekai, a framework for building social VR games built on the Godot 4 game engine
• Godot itself, while not explicitly VR-focused I think it has great potential for making VR content in the near future, and it’s also where I want to focus my efforts (I already made my first game, sorta lol)
• Hearth, I don’t understand it fully but what I gather is that it aims to be a shared virtual space, kinda like those “3D” desktops from the 90s but with multiple people and super extendable
• SlimeVR, open-source full-body trackers for VR. Mostly used in VRChat lol
• Stardust XR, a VR display server for Linux that supports stuff like widgets and filters (I think)

There’s tons more but I can’t think of all of them lmao, but there’s definitely cool stuff going on in the space and worth checking out.
