The first one worked with some kernel patches, there is a Discord server (Linux Adventures in VR) with lots of information about getting various headsets running in Linux.

If you are interested in Valve you might want to wait, rumor is we get at least an announcement very soon. I say this as someone that pre-order a Bigscreen Beyond 2 though, lol.

I currently am compiling Arch for Arm manually using some third party packages to run in distrobox on Asahi Linux (M1 Mac Fedora based distro). Hopefully this should mean I won’t need the manual compile step anymore, and hopefully we start seeing more general Arm support for more Linux apps.
