=== Nvidia PRIME ===

Official solution by nvidia. Currently, reverse PRIME does not work. The consequence of this is that if you have external display ports ~~that~~ are only exposed to the dedicated GPU, then running in offload mode [https://forum.manjaro.org/t/nvidia-render-offloading-help-getting-external-monitor-working/99430/23 will not allow you to use those display ports for external monitors]. If you wish to use the external monitors, you have to use sync mode.

The consequence of this is that if you have a special laptop configuration where external display ports are only exposed to the dedicated GPU, then running in offload mode [https://forum.manjaro.org/t/nvidia-render-offloading-help-getting-external-monitor-working/99430/23 will not allow you to use those display ports for external monitors]. If you wish to use the external monitors in that particular case, you have to use sync mode.

~~Firstly you need to enable the proprietary nvidia driver (or~~

You need to setup the Bus ID's of the cards as seen below.

~~{{file|/etc/nixos/configuration.nix|nix|<nowiki>~~

{

Note that on certain laptops and/or if you are using a custom kernel version, you may have issues with your NixOS system finding the primary display. In this case you should also specify modesetting in videoDrivers as well, i.e.

~~{{file|/etc/nixos/configuration.nix|nix|<nowiki>~~

{

~~services.xserver.videoDrivers = [ "modesetting" "nvidia" ];~~
