			If you are setting up it in your Flakes/Home-Manager configuration, you can use:

			<syntaxhighlight lang="nix">
			{
			outputs = { nixgl, nixpkgs, home-manager, ... }:
			let
			pkgs = import nixpkgs {
			system = "x86_64-linux"; # or "aarch64-linux"
			overlays = [ nixgl.overlay ];
			};
			in
			{
			homeConfigurations.penguin = home-manager.lib.homeManagerConfiguration {

			modules = [
			({ pkgs, ...}: {
			home.packages = with pkgs; [ nixgl.nixGLMesa ];
			})
			];
			};
			}
			}
			</syntaxhighlight>

			Using <code>nixgl.nixGLMesa</code> instead of <code>nixgl.auto.nixGLDefault</code> allow usage of pure evaluation.

			Afterwards, you can call programs with:

			<syntaxhighlight lang="console">
			$ nixGLMesa program
			</syntaxhighlight>

add initial wiki page for using Nix within Crostini

New page

This Wiki page describes the process required to get up and running on ChromeOs within Crostini. This does not talk about Crouton and assumes you have already installed Nix. [https://nixos.org/nix/manual/#chap-installation Guide to Installation].

Once you have Nix installed, there are a few things that need to be done.

== Home-Manager ==

Using [https://github.com/rycee/home-manager/ Home-manager] is pretty straight-forward, and is an easy way to manage Nix and install packages. The documentation on the Github repo is sufficient.

== Registering Applications with ChromeOs ==

This feature of Crostini expects .desktop files to be dropped in the appropriate places. (namely somewhere under <code>$XDG_DATA</code>).

Applications are registered with ChromeOs using a service running within the container called ''cros-garcon''. As it is a simple systemd service, we can easily extend it to look in nix-specific locations.

First we extend the service with new environment variables

<code>
mkdir -p ~/.config/systemd/user/cros-garcon.service.d/
</code>

followed by.

<code>
cat > ~/.config/systemd/user/cros-garcon.service.d/override.conf <<EOF
[Service]
Environment="PATH=%h/.nix-profile/bin:/usr/local/sbin:/usr/local/bin:/usr/local/games:/usr/sbin:/usr/bin:/usr/games:/sbin:/bin"
Environment="XDG_DATA_DIRS=%h/.nix-profile/share:%h/.local/share:/usr/local/share:/usr/share"
EOF
</code>

Then we need to restart our container. I found restarting the whole laptop to be the easiest and most effective method.

After this, we can simply start adding GUI packages to our home-manager configuration. Alternatively, if we are not using home-manager, then we can directly install packages:

<code>
nix-env -i slack
</code>
