+# 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.
