Valve has been Linux friendly. It says the new steam frame “is a PC” and will run Steam OS but I feel like there’s an insinuation that, like the steam deck, you can install whatever you like. I am cautiously excited at the premise of really digging in and having a Linux box strapped to my face.
Another friend has already referred to it as the Linux Vision Pro.
Edit: watching Linus tech tips review, it mentions side loading Android APKs as well
It’s a good start and has everything necessary for it, I guarantee a nice xr wayland compositor will exist for this in no time, and when they make the frame 2 it will likely be ready for xr as a usecase, all they really need is color passthrough and microoled, maybe higher fov and it’ll be there.
