External display (connected to dGPU) does not work

[abmantis]

My laptop has an Intel and an Nvidia. The external display port is connected to the Nvidia. Despite having the Intel as the main GPU (doing the rendered), the Nvidia is used to render frames on the external display when one is connected (no prime or bumblebee needed).

I am trying to use Hyprland with nixGL and I can only get the internal display to work. I have tried nixGLIntel nixGLNvidia-.... Hyperland but it still does not work.
