Hi
I got problem to detect the external HDMI port with xrandr command.
I have tried these parameters options nvidia-drm modeset=0, options nvidia-drm modeset=1 but still can not detect.

Here is the log with diferent parameters

Please remove
Option “UseDisplayDevice” “none”
from your xorg.conf.

Thanks for response so quickly.

I already remove the UseDisplayDevice option from nvidia-xorg.conf, and I also check there is no UseDisplayDevice option in xorg.conf. Then, I also try different modeset parameters, modeset=0 and modeset=1. But the external HDMI is still not detected by xrandr.

Here are the logs.

I do not have privacy concern at this moment, and also willing to provide more information via Zoom or other communication tools and/or run any other futher scripts if you are want to get more details.
Many thanks.

/etc/X11/nvidia-xorg.conf.d/30-nvidia.conf
still has
Option “UseDisplayDevice” “none”
set. Please remove it.
