I did a fresh install of Debian 12 on my laptop.
SecureBoot always became disabled.

My laptop hardwares are as follows:

KERNEL : 6.1.0-37-amd64

CPU : Intel(R) Core(TM) i7-9750H CPU @ 2.60GHz (12 Core)

GPU : 00:02.0 VGA compatible controller: Intel Corporation CoffeeLake-H GT2 [UHD Graphics 630]
01:00.0 VGA compatible controller: NVIDIA Corporation TU116M [GeForce GTX 1660 Ti Mobile] (rev a1)

ENVIRONMENT : GNOME

I successfully installed the nvidia-driver package which i downloaded from NVIDIA’s website. Before i installed i was able to use my laptop’s main monitor and other external monitor. After install my laptop’s monitor working only at grub, and all the other time i am using second monitor. Even if i plug out the second monitor still laptop giving me black screen.

Setup and environment information

All commands and output provided below were ran with the external monitor connected to the laptop.

What I have tried

set kernel parameter
nvidia-drm.modeset=1
and reboot, then run
xrandr --setprovideroutputsource NVIDIA-G0 modesetting && xrandr --auto
Reply from terminal: Could not find provider with name NVIDIA-G0

You use X11 not Wayland, correct? Assuming so, most probably X has not autoconfigured itself to use displays connected to the Intel GPU. Try configuring it manually by adding a file with the following contents somewhere in /etc/X11/xorg.conf.d/ folder:

Section "Device"
        Identifier "Intel"
        Driver "modesetting"
        BusID "PCI:0:2:0"
EndSection

Section "Device"
        Identifier "Nvidia"
        Driver "nvidia"
        Option "AllowEmptyInitialConfiguration" "true"
        BusID "PCI:1:0:0"
EndSection

Section "Screen"
        Identifier "dualGPU"
        Device "Nvidia"  ## primary GPU performing the rendering
        GPUDevice "Intel"  ## secondary GPU providing additional monitors
EndSection

On a side note:

This was released in 2022… I think there are some newer kernels available in backports, but generally Debian-12 is a pretty old system. I’d recommend going with Debian-13 which is currently in RC stage and has been perfectly stable for over a year now. You can then use Nvidia apt repos for Debian-12: they work fine with 13 as well.
