545.29.06 on Arch Wayland RTX3080+GT1030 2 our of 6 monitors no output

I am using Arch linux using Wayland with two dGPUs, rtx 3080 & gt 1030, with four monitors connected to rtx 3080 and two connected to gt1030.

There is no output for the two monitors that are connected to gt1030. The four rtx 3080 ones works fine.

sudo cat /sys/module/nvidia_drm/parameters/modeset returns Y.

nvidia-smi returns the following:

You’re using Hyprland as compositor, seems it doesn’t support multi-gpu, multi-monitor with nvidia:
