Hi! I'm not sure if you're just trying to install Stylix, or if this is a new issue as a result of recent updates.

Do you have any other Stylix settings in your nixos/configuration.nix?

If you're installing Stylix for the first time, then from the config you've provided, it looks like you'll need to do the following:

1. Move your Stylix settings from home.nix to configuration.nix, since you imported the NixOS version of Stylix.
2. Choose a wallpaper using stylix.image.

Same result, if i try adding the image it says

Directory is valid

[MercuryHgO]

Is it necessary to add wallpaper to config?

My fault, but even if i add the image, it says this:

That error sounds like it's trying to import the image as if it was Nix code.

How did you set the wallpaper option?

Yea, im accidentally imported as import ./wallaper.png.

Its still not processing this image if configures as absolute path:

  stylix = {
    enable = true;
    base16Scheme = "${pkgs.base16-schemes}/share/themes/gruvbox-dark-medium.yaml";
    image = "/home/bittermann/nix/nixos/wallpaper.png";

Try configuring it as a relative path without quotes, like this: ./wallpaper.png

It will need to be in the same directory as your Nix files.

[geryzhydrox]

Hey there, I've had various arcane errors with Stylix that I've tried - and failed - to get help with on Element, but now after switching to flakes my error message has switched to something that apparently at least someone else has too, error: The option 'stylix.image' is used but not defined.. I'm trying the same things now and am still stuck at that error.

[MercuryHgO]

That fixed my issue, thanks. But still, is it should be necessary to define wallpaper?

[MasonRhodesDev]

I'd like to add that I experienced this issue after updating my flake with nix flake update It seems the recent(?) change that requires you set stylix.enable may have caused stylix.image not to be defined anymore.

I added stylix.enable = true; to my configuration.nix to solve the issue.

[trueNAHO]

But still, is it should be necessary to define wallpaper?

See https://github.com/danth/stylix/issues/200.

[joefiorini]

I have what I believe to be the latest stylix and the latest nix-darwin. I'm getting error: The option 'stylix.image' is used but not defined. as well when trying to use nix-darwin switch.

I noticed the error actually occurs at: /nix/store/c5d7z0g0mqdvqanndgcfxcffvkcn4ymd-source/stylix/home-manager-integration.nix. Based on that, is it breaking because the home-manager config doesn't have defs for stylix?

Here is the relevant subset of my nix flake metadata output:

[georgealexanderday]

Even when setting an image but specifying base16 theme, I'm seeing no/wrong application of themes with no build errors, think something might be afoot here but haven't had the chance to investigate further yet.

If by "no/wrong", you mean that Stylix is not actually doing anything, consider reading https://github.com/danth/stylix/issues/417#issuecomment-2157942224.

[RekitRalph]

I am encountering a similar issue. if I do not define stylix.enable = true; along with the wallpaper and color theme, in the configuration.nix I get the same error: The option 'stylix.image' was accessed but has no value defined. Try setting the option.

I thought I could just put the options in home.nix instead of configuration.nix is the correct?

Here is my flake.

outputs = inputs@{ self, nixpkgs, home-manager, ... }: {

    nixosConfigurations = {

      nixos = nixpkgs.lib.nixosSystem {
        system = "x86_64-linux";
        modules = [
          ./configuration.nix
          inputs.stylix.nixosModules.stylix

          home-manager.nixosModules.home-manager
          {
            home-manager.useGlobalPkgs = true;
            home-manager.useUserPackages = true;
            home-manager.users.evan = import ./home/home.nix;

            # Optionally, use home-manager.extraSpecialArgs to pass
            # arguments to home.nix
          }
        ];
      };
    };
  };

[danth]

It's the other way around - you can use configuration.nix and the settings will automatically be copied to Home Manager.
