Hi
I have an Asus FX505DV AMD Ryzen 5 3550H with Radeon Vega Mobile Gfx with a NVIDIA TU106M [GeForce RTX 2060 Mobile] card.
When i use the nvidia drivers (by removing the # from in front of the Option "PrimaryGPU" "Yes" line in /etc/X11/xorg.conf.d/10-nvidia.conf ). Lightdm wants to display on the hdmi rather than the laptop monitor even when there is no monitor plugged into the hdmi port.
/etc/X11/xorg.conf.d/10-nvidia.conf
Output of
Section "OutputClass"
Identifier "nvidia"
MatchDriver "nvidia-drm"
Driver "nvidia"
Option "AllowEmptyInitialConfiguration"
Option "PrimaryGPU" "Yes"
ModulePath "/usr/lib/x86_64-linux-gnu/nvidia/xorg"
