[Fedora] [Nvidia] Fresh install, DisplayPort monitor not recognized
Set the DisplayPort version in the G9's on-screen menu to 1.2, replug the cable, and check whether xrandr shows that DP output as connected.
If it still shows disconnected, replug the cable and right after run:
sudo journalctl -k -b | grep -i -E 'nvidia|drm'
Look for link training or EDID errors on that connector.
Also run cat /sys/module/nvidia_drm/parameters/modeset and confirm it returns Y.
