SteamVR isn't detected

[BukuTavle]

When I launch ALVR i get this error and when i click on Launch SteamVR, it gives the error you see on the bottom again. I know I have SteamVR installed and that I can launch it normally. I'm on Debian 12, kde plasma, wayland. I have the flatpak version of steam installed if that means anything. Here are the error logs:

I don't get error message, but Steam VR 2.9 home 3D world doesn't show up in the HMD. It was working with a bad height setting before version 2.9.

Are you using flatpak alvr or desktop alvr? If you are using flatpak steam, and trying to use non-flatpak alvr, it will not work.

it worked but now i have this error. Is that problemattic?

If you're using intel igpu with dgpu, you either disable igpu or use commands as said in logs (that should also say about steamvr) on steamvr
