Is your issue getting it to start at all, or performance issues?
For me it wouldnt start at all in the default big picture mode and would only start in desktop mode.
I made a few tweaks to get performance tuned up when I was on the Vega64, but I don’t remember what all I did there.
edit: Also, I’m the KDE desktop (i wanted my HTPC/VRPC to be as steamdeck similar as possible, and also I have strong anti gnome feelings).
This lightning talk requires running SteamVR for the room setup bits, and it recommends a few things in the name of “user friendliness” that I would otherwise not suggest (Ubuntu bad, Gnome bad, etc). (edit: so switching to Monado wouldn’t really help since it would require SteamVR working in the first place, and if SteamVR works… OP could just use SteamVR)
But it does show a lot of problems and solutions and things to try along the way.
Based on https://db.vronlinux.org/ (which is like protondb for VR, kinda), monado works better for VRChat, but otherwise SteamVR should honestly work just fine.
