Black screen on secondary screen

Hello everyone,

I'm trying to get my second screen to be my primary screen so I can keep my laptop closed. Sadly, when I connect it via Displayport it just remains point blank. I've tried so many xrandr commands that I found on the internet but still nothing succeeds.
Here's my xrandr output:

Maybe this information is also needed: my computer is an ROG Strix Laptop with (sadly) an NVIDIA RTX 3050 and AMD integrated graphics.

Would love to get some help on this.

Re: Black screen on secondary screen

Please wrap output in code instead of quote tags

General sanity checks, make sure and double check both ends are plugged in, that the other monitor is actually on and on the correct input device channel (and maybe test it on another system you're "sure" it should be working on)

Post your xorg.log. Did you create any specific configuration for xorg? Chances are the port is connected to the nvidia card, so you should install the proprietary nvidia driver and follow: https://wiki.archlinux.org/title/PRIME# … er_offload

If you're currently using xf86-video-amdgpu you might want to remove that as the modesetting driver is more tested with the offloading method that has to happen here.

Re: Black screen on secondary screen

I didn't create any configuration for xorg, just as it comes with archinstall. I also do not have a xorg.log anywhere on my system. I installed the nvidia driver and followed the steps on the wiki but still nothing. How do I remove the amdgpu?

Re: Black screen on secondary screen

You'd remove it with

pacman -R xf86-video-amdgpu

Post the xorg log and for that matter a system journal

sudo journalctl -b

Re: Black screen on secondary screen

I don't have the amd gpu installed, but I now after 2 hours have managed to change my nvidia drm mode to 1, now everything works as intended. Thanks for your try to help me! Appreciate it.

Re: Black screen on secondary screen

Yeah sorry that's generally somewhat of a precondition I should've suggested that earlier. It shouldn't be strictly necessary which is why I'd rather wanted some other log first, but it's generally a good idea to have that enabled regardless.

Please mark as [SOLVED] by editing the title in your first post.
