For me it does something similar most of the time

I plug the headset in, start streamvr, and it falls to connect to the headset display, with red lights on the headset

What fixes it for me is just hitting quilt vr on the steamvr window, unplugging the headset, plugging it back in and then starting steamvr

Then it usually works

In my experience after reboots, or after extended periods of time without running vr, I have to do this dance to get it to work, I don’t know why

I’m running an RTX 3090 with the proprietary drivers on Arch KDE X11, with the native (non flatpak) steam package
