[SOLVED] xrandr does not recognize HDMI screen (NVIDIA)

I've intel graphic card and NVIDIA RTX 3050 in my Laptop, I swiched to Arch recently and can't get my HDMI external monitor to work, it is not recognized by xrandr at all. I think nVidia drivier works well

xrandr output

Re: [SOLVED] xrandr does not recognize HDMI screen (NVIDIA)

Your xorg config  disables the nvidia driver (driving the HDMI out) and your alternate config disables the intel driver (driving the laptop display).

The solution here is not trying to be fancy, get rid of your config and boot without it. xorg will detect and logically setup both gpus correctly. You might be interested in https://wiki.archlinux.org/title/PRIME# … er_offload and the prime-run utility for selecting the rendering card for applications. You might want to setup modesetting on the nvidia card to enable PRIME sync working correctly:  https://wiki.archlinux.org/title/PRIME# … ronization

Re: [SOLVED] xrandr does not recognize HDMI screen (NVIDIA)

yes. If things still don't work, post a xorg log of trying it without any config.

	Using the first device section listed.
[     5.590] (**) |   |-->Device "integrated"
grep -r integrated /{etc,usr/share}/X11/xorg.conf*

Do you use optimus-manager?

Re: [SOLVED] xrandr does not recognize HDMI screen (NVIDIA)

You need to stop flailing around  - you're creating a mess and a moving target.
Then yes: remove optimus-manager and post an updated xorg log and also system journal to illustrate where you are right now.

Re: [SOLVED] xrandr does not recognize HDMI screen (NVIDIA)

Remove every xf86-video-* package and re-install the nvidia drivers and enable https://wiki.archlinux.org/title/NVIDIA … de_setting - use the "nvidia_drm.modeset=1" kernel parameter.
Nouveau has issues driving your GPU and crashes the X11 server.

Edit: then report back w/ an updated xorg log

Re: [SOLVED] xrandr does not recognize HDMI screen (NVIDIA)

but i added thsi to xrog.cong

In theory that should not be necessary - what does the xorg log look w/o it?

Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.
