Getting started with Stylix and KDE Plasma 5

[oscar-schwarz]

Hello stylix community,

My Nix configuration uses KDE Plasma 5, and I want to use stylix for obvious reasons. So I included stylix how it is described in vimjoyers Video.

# flake.nix
{
  # ...
  inputs = {
    # ...

    stylix = {
      url = "github:danth/stylix";
      inputs.nixpkgs.follows = "nixpkgs";
      inputs.home-manager.follows = "home-manager";
    };
  };

  outputs = { self, nixpkgs, ... }@inputs: {
    nixosConfigurations.default = nixpkgs.lib.nixosSystem {
      specialArgs = {inherit inputs;};
      modules = [
        # ...
        inputs.stylix.nixosModules.stylix
      ];
    };
    # ...
  };
}

# configuration.nix
# ...
  stylix = {
    base16Scheme = "${pkgs.base16-schemes}/share/themes/still-alive.yaml";
    image = ./images/nms.jpg;
    polarity = "dark";
    cursor.size = 100;
    autoEnable = true;

    opacity = {
      desktop = 0.5;
    };
  };
# ...

Even though I have set it all and rebuild switch works without errors, nothing changes in my setup (even after a logout). In the Readme it also says "some manual steps may be needed" to make stylix work on KDE. What would be these steps?

Firstly, check that home-manager-《username》.service finished successfully. If it didn't, remove any conflicting files and try to restart it.

I solved my problem, that was the error I got:

Just as the error says make sure to set home-manager.backupFileExtension = "backup" in your configuration.nix.
