Nvidia

Good luck. ## Installation

Arch: install the nvidia package.

Configuration

Minimal xorg setup for only running on Nvidia GPU

This minimal configuration should get you started. Add this in /etc/X11/xorg.conf.d in a file similar to 10-nvidia-drm-outputclass.conf

Section "OutputClass"
    Identifier "intel"
    MatchDriver "i915"
    Driver "modesetting"
EndSection

Section "OutputClass"
    Identifier "nvidia"
    MatchDriver "nvidia-drm"
    Driver "nvidia"
    Option "AllowEmptyInitialConfiguration"
    Option "PrimaryGPU" "yes"
    ModulePath "/usr/lib/nvidia/xorg"
    ModulePath "/usr/lib/xorg/modules"
EndSection

Scaling without overscan on PRIME displays

If you cannot use xrandr --scale without leading to over/underscan you need to adjust a kernel parameter:

create a file in /etc/modprobe.d (for example called nvidia-drm-nomodeset.conf) with the following content.

options nvidia-drm modeset=1

and rebuild your kernel via

sudo mkinitcpio -P

After a reboot this should enable scaling for PRIME displays.
