Budgie Desktop
From NixOS Wiki
The Budgie Desktop is a feature-rich, modern desktop designed to keep out the way of the user.
Installing Budgie Desktop
To use the Budgie Desktop, add this to your configuration.nix:
services.xserver.enable = true;
services.xserver.desktopManager.budgie.enable = true;
services.xserver.displayManager.lightdm.enable = true;
Excluding some Budgie Desktop applications from the default install
Not all applications that come pre-installed with the Budgie Desktop are desirable for everyone to have on their machines. There's a way to edit configuration.nix to exclude these kinds of packages, for example as follows:
environment.budgie.excludePackages = with pkgs; [
mate.mate-terminal
vlc
];
