# 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`
```xf86config
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.
```xf86config
options nvidia-drm modeset=1
```
and rebuild your kernel via
```sh
sudo mkinitcpio -P
```
After a reboot this should enable scaling for PRIME displays.
