External Monitor on HDMI with a Hybrid (Nvidia Optimus) laptop

Question

Linux - Debian uname -a >> output

Linux HomeLT 4.19.0-6-amd64 #1 SMP Debian 4.19.67-2+deb10u2 (2019-11-11) x86_64 GNU/Linux

I have a ASUS TUF FX504 GM. It has a Intel i7 8750H and a GTX 1060 The problem is .. I can't use the external monitor I would plug into the HDMI port, by default. The Intel iGPU, UHD 630 is the default one that gets used unless I use this config file as specified in the following guide..

I have the "nvidia-driver" package installed.

http://us.download.nvidia.com/XFree86/Linux-x86/375.26/README/randr14.html

/etc/X11/xorg.conf.d/10-nvidia.conf

Section "ServerLayout"
    Identifier "layout"
    Screen 0 "nvidia"
    Inactive "intel"
EndSection

Section "Device"
    Identifier "nvidia"
    Driver "nvidia"
    BusID "PCI:1:0:0"
EndSection

Section "Screen"
    Identifier "nvidia"
    Device "nvidia"
    Option "AllowEmptyInitialConfiguration"
EndSection

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

Section "Screen"
    Identifier "intel"
    Device "intel"
EndSection

Is there anyway to change this file to make it so that the computer books on the intel screen.. but also keeps the nvidia drivers "inactive" so that both monitors show up when I run the command "xrandr --auto"

I tried putting

Screen 0 "intel"
Inactive  "nvidia"

But that doesn't work. Tried

Screen 0 "intel"
Screen 1 "nvidia

" without the inactive line. That didn't quite work either.

I also have to run

xrandr --setprovideroutputsource modesetting NVIDIA-0
xrandr --auto

after start up.

Can anyone help?

A bit late but according to the documentation the BusID format is

"%d@%d:%d:%d", bus, domain, device, function

I would try to replace the first : with a @.

See NVIDIA's FAQ: "What is the format of a PCI Bus ID?"
