Firstly you need to enable the proprietary nvidia driver | |||
{{file|/etc/nixos/configuration.nix|nix|<nowiki> | {{file|/etc/nixos/configuration.nix|nix|<nowiki> | ||
{ | { | ||
services.xserver.videoDrivers = [ "nvidia" ]; | services.xserver.videoDrivers = [ "nvidia" ]; | ||
... | |||
</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 intel in videoDrivers as well, i.e. | |||
{{file|/etc/nixos/configuration.nix|nix|<nowiki> | |||
{ | |||
services.xserver.videoDrivers = [ "intel" "nvidia" ]; | |||
... | |||
</nowiki>}} | |||
Then you need to setup the Bus ID's of the cards as seen below | |||
{{file|/etc/nixos/configuration.nix|nix|<nowiki> | |||
... | |||
hardware.nvidia.optimus_prime.enable = true; | hardware.nvidia.optimus_prime.enable = true; | ||
# Bus ID of the NVIDIA GPU. You can find it using lspci | # Bus ID of the NVIDIA GPU. You can find it using lspci, either under 3D or VGA | ||
hardware.nvidia.optimus_prime.nvidiaBusId = "PCI:1:0:0"; | hardware.nvidia.optimus_prime.nvidiaBusId = "PCI:1:0:0"; | ||
# Bus ID of the Intel GPU. You can find it using lspci | # Bus ID of the Intel GPU. You can find it using lspci, either under 3D or VGA | ||
hardware.nvidia.optimus_prime.intelBusId = "PCI:0:2:0"; | hardware.nvidia.optimus_prime.intelBusId = "PCI:0:2:0"; | ||
} | } | ||
</nowiki>}} | </nowiki>}} | ||
An example of a final configuration is below | |||
{{file|/etc/nixos/configuration.nix|nix|<nowiki> | |||
{ | |||
services.xserver.videoDrivers = [ "intel" "nvidia" ]; | |||
hardware.nvidia.optimus_prime.enable = true; | |||
# Bus ID of the NVIDIA GPU. You can find it using lspci, either under 3D or VGA | |||
hardware.nvidia.optimus_prime.nvidiaBusId = "PCI:1:0:0"; | |||
# Bus ID of the Intel GPU. You can find it using lspci, either under 3D or VGA | |||
hardware.nvidia.optimus_prime.intelBusId = "PCI:0:2:0"; | |||
} | |||
</nowiki>}} | |||
