Running VR on NixOS requires an understanding of the interaction between OpenXR runtimes, compositors, and the Steam sandbox. For the Meta Quest 3S + Steam (Proton) setup, the optimal and most stable solution is using WiVRn as the streamer and OpenXR runtime, with optional OpenComposite for backward compatibility with older OpenVR titles. 💡 Critically important: VR packages in NixOS evolve rapidly. It is highly recommended to use packages from the nixos-unstable branch or the nixpkgs-xr overlay. ...
