I get an error message when I run “nvidia-setting”

That’s normal, just ignore.

How can I switch to Nvidia GPU? it doesn’t have “Prime Profile” in “Nvidia Settings”.

prime-select etc. is Ubuntu specific. With debian, please check:

When I set Nvidia as primary GPU
and add script in rc.local file
xrandr --setprovideroutputsource modesetting NVIDIA-G0 && xrandr --auto

It shows black screen.

$ xrandr --listproviders
Providers: number : 2
Provider 0: id: 0x45 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 3 outputs: 3 associated providers: 0 name:modesetting
Provider 1: id: 0x230 cap: 0x0 crtcs: 0 outputs: 0 associated providers: 0 name:NVIDIA-G0

10-nvidia-primary.conf :

Section "OutputClass"
    Identifier "nvidia"
    MatchDriver "nvidia-drm"
    Driver "nvidia"
    Option "PrimaryGpu" "yes"
    Option "AllowEmptyInitialConfiguration" "true"
EndSection

Running the commands in a rc script doesn’t work, the DM has to run them:
