* [https://nixos.org/manual/nixos/unstable/#sec-x11-graphics-cards-nvidia Nvidia section] in the NixOS Manual offers a shorter guide.

* Basic installation is as simple as <code>services.xserver.videoDrivers = [ "nvidia" ];</code> (once you have unfree software enabled), which causes the default stable version to be pulled in.

* Older cards may need an older driver; see [[#Determining the correct driver version]], which describes <code>hardware.nvidia.package</code>.

* Older cards may need an older driver; see [[#Determining the correct driver version|Determining the correct driver version]], which describes <code>hardware.nvidia.package</code>.

* [[#Modifying the NixOS Configuration]] puts it all together and shows the other <code>hardware.nvidia</code> settings, some irrelevant to this driver (e.g. <code>hardware.nvidia.open</code>, which takes you to the Nvidia open kernel driver.)

Make sure to allow [[Unfree ~~Software~~|unfree software]]. The unfree NVIDIA packages include <code>nvidia-x11</code>, <code>nvidia-settings</code>, and <code>nvidia-persistenced</code>.

=== Running Specific NVIDIA Driver Versions ===

To run a specific version of the NVIDIA driver in NixOS, you can customize your configuration by specifying the desired version along with the corresponding SHA256 hashes. Below is an example configuration for using NVIDIA driver version `555.58.02`:

{{file|/etc/nixos/nvidia.nix|nix|<nowiki>

package = config.boot.kernelPackages.nvidiaPackages.mkDriver {

version = "555.58.02";

sha256_64bit = "sha256-xctt4TPRlOJ6r5S54h5W6PT6/3Zy2R4ASNFPu8TSHKM=";

sha256_aarch64 = "sha256-xctt4TPRlOJ6r5S54h5W6PT6/3Zy2R4ASNFPu8TSHKM=";

openSha256 = "sha256-ZpuVZybW6CFN/gz9rx+UJvQ715FZnAOYfHn5jt5Z2C8=";

settingsSha256 = "sha256-ZpuVZybW6CFN/gz9rx+UJvQ715FZnAOYfHn5jt5Z2C8=";

persistencedSha256 = lib.fakeSha256;

};

</nowiki>}}

In this configuration:

* Replace `version` with the desired driver version.

* Update the SHA256 hashes to match the new version you want to use.

* After updating the configuration, run <code>sudo nixos-rebuild switch</code> to apply the changes and load the specified NVIDIA driver version.

This allows you to pin the specific driver version being used in your NixOS installation.

Be warned that the Nvidia open driver is considered "beta quality". Performance may be very slightly lower.

(Update to be incorporated: Nvidia has [https://developer.nvidia.com/blog/nvidia-transitions-fully-towards-open-source-gpu-kernel-modules/ announced in July 2024] that the upcoming version R560 will "fully transisition" towards the open-source kernel module. This means that the default kernel module installed by Nvidia scripts will be the open-source one. This is justified as the open-source driver is now as stable and performant as (if not more than) the closed-sourced driver. The new driver only applies to Turing and later GPUs; older hardware with Maxwell, Pascal, or Volta will still require the proprietary version.)
