treewide: enable DConf if used in HM module

[brckd]

The GTK module for NixOS enables DConf in order for the Home Manager module to take effect.

https://github.com/nix-community/stylix/blob/4a8718e5a14faeef3e57ededb4efb88b0deed329/modules/gtk/nixos.nix#L8-L9

The same should be done for the eog and gnome-text-editor targets, which contain DConf settings, but have no matching NixOS module.

Do you mean that the Home Manager modules should programs.dconf.enable = true;? AFAIK, Home Manager is unable to install this system setting. The dconf.settings Home Manager option might be useful.

If you mean that we should add corresponding NixOS modules containing programs.dconf.enable = true;, then they should only do that when detecting that the corresponding Home Manager module is enabled. Although, I am unsure whether this detection is possible or how easy it would be.

Yes, this is what I meant. However, the NixOS module for GTK enables DConf only if that module is enabled, regardless of the state of the HM module. I'd argue we could do the same for the sake of consistency.

[danth]

I would argue for removing the GTK one, or replacing it with a warning when possible (based on osConfig within integrated Home Manager).

We don't usually enable programs on behalf of the user. (This code is a relic from the early days of Stylix.)

[brckd]

Sure, that sounds like a viable option! The purpose of this PR was to create consistency, so I'm open to going the other way around.

Hi there,

I' m having troubles on Hyprland. I didn' t find a way to fix it. Here is a summary:

Config

System: NixOS 25.05
DE/WM: Hyprland (not GNOME)
Home Manager

Changes

flake.nix:

stylix = {
  url = "github:danth/stylix/release-25.05";

What I tried

• Added programs.dconf.enable = true; in Home Manager config → error persists.

• Imported Home Manager’s dconf module directly:

imports = [ "${home-manager}/modules/programs/dconf.nix" ];

→ error persists.

• dconf enabled system wide → error persists.

Expectation

Since I’m not using GNOME (Hyprland only), I would expect Stylix to not require dconf / GNOME modules. I even explicitly disabled targets.gnome-text-editor and targets.gnome-shell, but Stylix still tries to evaluate them.

Questions

Am I missing something?

[danth]

@bourdeau It looks like you're importing Stylix's Home Manager module into NixOS, rather than Home Manager. Try replacing stylix.homeModules.stylix in your flake.nix with stylix.nixosModules.stylix. This should automatically set up Stylix in Home Manager as well.

[bourdeau]

@danth Thanks a lot for your answer. You are right, I did' t pay attention. I will give it a shot tomorrow and keep you updated.
