Can't connect to external display over USB-C or HDMI

I've just bought a new laptop with an AMD Ryzen 9 5000HS and an Nvidia RTX 3060. The laptop has HDMI and two USB-C none of them show up when I run xrandr --listproviders. the output is:

 Providers: number : 1
Provider 0: id: 0x55 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 4 outputs: 2 associated providers: 0 name:Unknown AMD Radeon GPU @ pci:0000:04:00.0

Providers: number:

always is 1 no matter wich port I use. I've installed the xf86-video-amdgpu and the xf86-video-nouvaue drivers. Anyone got an idea what I could do?

Please format the output properly with code tags.
I suspect support from nouveau for your card is still in its infancy, so probably better to use the proprietary NVIDIA driver. Refer to https://wiki.archlinux.org/title/NVIDIA#Installation for installation and more.

... And more specifically since this looks like an Optimus setup: https://wiki.archlinux.org/title/PRIME# … er_offload

Re: Can't connect to external display over USB-C or HDMI

Hi I'm back, I''ve had some problems with nvidia-xconfig and at the end I reinstalled my system. After that I followed this website and my second monitor now is recognized, unfortunatly I've got problems with scaling, I'd like to use an 0.6x0.6 scale for one Monitor and no scale for the other. I'm trying to do this with this command in my .xinitrc:

xrandr --output DP-0 --primary --scale 0.6x0.6 --mode 3440x1440 --pos 0x0 --rotate normal --output DP-1 --off --output eDP-1-0 --mode 2560x1440 --pos 440x1440 --rotate normal --output HDMI-A-1-0 --off

but except that rofi isn't centered after this nothing happens. Most of the command I got from the arandr gui.
