VR on linux is scuffed. https://lvra.gitlab.io/ refer to this site for vr on linux. If you play VRchat, its pretty much unplayable in vr on linux, its literally somehow a better experience on quest standalone
Try WiVRN, it's not built on SteamVR, and doesn't have the same issues SteamVR does. You can get it through a flatpak or by using Envision, as described on the LVRA wiki.
I don't play VRChat myself, but I have to disagree. I'm in several Linux VR groups, and the general sentiment is that it's not as easy to set up, but works well for the more popular games, including VRChat. This is similar to my experience. There's good resources (like LVRA) to help people set things up, or when they're running into issues. I'm also not saying VR on Linux is flawless, far from it, but to describe it as just "scuffed" without context doesn't explain the whole state of it.
