Black screen on log screen

Hi

I have an Acer Nitro 5 AN515-44 with a processor AMD Ryzen 5 4600H and graphic cards GTX 1650 TI (4 Go) & AMD Radeon Vega 6.

When installing Ubuntu 20.04, at first i could’nt set luminosity of my laptop. I solved this problem by upgrading to the kernel 5.8.0-33 with command :

sudo apt install linux-generic-hwe-20.04-edge

Then i wanted to connect my lapto to my external monitor but it was not recognised at first. I finally solved my problem by adding Option “PrimaryGPU” “Yes” to the file /usr/share/X11/xorg.conf.d/10-nvidia.conf and by replacing Driver “amdgpu” with Driver “modesetting” to the file /usr/share/X11/xorg.conf.d/10-amdgpu.conf like this :

/usr/share/X11/xorg.conf.d/10-nvidia.conf
Section “OutputClass”
Identifier “nvidia”
MatchDriver “nvidia-drm”
Driver “nvidia”
Option “AllowEmptyInitialConfiguration”
Option “PrimaryGPU” “Yes”
ModulePath “/usr/lib/x86_64-linux-gnu/nvidia/xorg”
EndSection

/usr/share/X11/xorg.conf.d/10-amdgpu.conf
Section “OutputClass”
Identifier “AMDgpu”
MatchDriver “amdgpu”
#Driver “amdgpu”
Driver “modesetting”
EndSection

But i just figured out by rebooting my laptop (without extetnal monitor connected) that Lightdm want to display HDMI instead of the screen of the laptop.
The consequence is the the screen of the laptop stays black on the login screen. Fortunaly, i can type my password (blind). Once password validated, the OS understand there is no monitor on HDMI and displays the screen of the laptop.
Important point, in Nvidia-settings the monitor number 1 is the external monitor, not the one of my laptop. And i can’t change it.

Does anyone already had this problem ?

I put some results to help.

Best regards,

Jimmy
