nix run github:dp0sk/adw-gimp3

to launch a version of GIMP 3.0 with adw-gimp3 built in.

Installation

Note

This theme depends on adw-gtk3 installation, for non-NixOS systems. Follow the instructions there before proceeding with adw-gimp3 installation.

Manual Installation

adw-gtk3

1. Install the adw-gtk3 theme first.

2. Enable the adw-gtk3 theme via one of the following:

• GNOME Tweaks
• Refine
• Run: gsettings set org.gnome.desktop.interface gtk-theme 'adw-gtk3'

adw-gimp3

1. Download the adw-gimp3 repository

   git clone https://github.com/dp0sk/adw-gimp3
   cd adw-gimp3

2. Install the theme to your config directory by either running the installation script (install.sh) OR manually copying the adw-gimp3 folder to ~/.config/GIMP/3.0/themes/:

   mkdir -p ~/.config/GIMP/3.0/themes
   cp -r adw-gimp3 ~/.config/GIMP/3.0/themes

3. Launch GIMP

4. Navigate to Edit → Preferences → Theme

5. Select the adw-gimp3 theme.

Configuring flatpak

Note

install.sh will handle the flatpak configuration automatically.

Warning

Flatpak doesn’t apply your system themes by default. To enable them, follow these steps:

1. Install Flatseal
2. Navigate to All applications (global) → Filesystem → Other files
3. Add these lines:
   • xdg-config/gtk-3.0:ro
   • xdg-config/gtk-4.0:ro
4. Now all your flatpak apps will be themed!

Nix / NixOS

NixOS, nix-darwin, & home-manager users can use the provided modules to install GIMP pre-loaded with the adw-gimp3 theme in your environment configs:

{
  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-24.11";
    nix-darwin.url = "github:LnL7/nix-darwin/nix-darwin-24.11"
    home-manager.url = "github:nix-community/home-manager";
    adw-gimp3.url = "github:dp0sk/adw-gimp3";
  };
  outputs = inputs@{ nixpkgs, nix-darwin, adw-gimp3, ... }: {
    # Install system-wide on a nix-darwin system:
    darwinConfigurations."Johns-Macbook" = nix-darwin.lib.darwinSystem {
      modules = [adw-gimp3.darwinModules.default];
    };

    # Install system-wide on a NixOS system:
    nixosConfigurations.my-host = nixpkgs.lib.nixosSystem {
      modules = [adw-gimp3.nixosModules.default];
    };

    # Install in your user home environment:
    homeConfigurations.my-home = home-manager.lib.homeConfiguration {
      modules = [adw-gimp3.homeManagerModules.default];
    };
  };
}

or install GIMP 3.0 with adw-gimp3 to a profile:
