Vr not working correctly, drm leasing issue

Do you get any error when running steam vr with the launch option?
So when I set the launch options and the connection type as TCP I get the error

error in encoder thread: Failed to transfer Vulkan image to CUDA frame Generic error in an external library

But the controlers and headset get recognised but still a Black screen.

When I set the connection type to udp i don’t get the error but therfor the controllers and the headset don’t get recognised.

I get the feeling you’re mixing nixpkgs revisions here.

Which exact revision of nixpkgs is this and is it the exact same nixpkgs revision that the currently deployed NixOS is built from?

Mixing nixpkgs revisions can work for simple CLI stuff but is extremely likely to fall apart for anything that has to do with graphics; even if it’s two revisions from the “same” channel.

Please use exactly one nixpkgs revision.

sorry i couldnt reply yesterday because of the limit for new users

do you mean because im on nixos 24.11 and i installed alvr on unstable?

Yes, that’s very likely to cause issues.

Take everything from the exact same revision of nixpkgs.
