== Graphical applications == | |||
Thanks to the usage of VirtGL as the GPU driver, you can easily run applications that depend on OpenGL/Vulkan by using [https://github.com/nix-community/nixGL NixGL]: | |||
<syntaxhighlight lang="console"> | |||
$ nix run --impure github:guibou/nixGL -- program | |||
</syntaxhighlight> | |||
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 { | |||
inherit pkgs; | |||
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> | |||
