How it works#

Linux (KDE Plasma)#

plasma-manager's workspace.wallpaper option applies wallpaper via D-Bus at home-manager activation time. However, activation runs before the Plasma session is live, so D-Bus isn't available and it silently fails.

Instead, a systemd.user service in home/programs/kde.nix calls plasma-apply-wallpaperimage after plasma-plasmashell.service is up:

systemd.user.services.set-plasma-wallpaper = {
  Unit.After   = [ "plasma-plasmashell.service" ];
  Unit.PartOf  = [ "graphical-session.target" ];
  Service.Type = "oneshot";
  Service.ExecStart = "${pkgs.kdePackages.plasma-workspace}/bin/plasma-apply-wallpaperimage ${wallpaper}";
  Install.WantedBy  = [ "graphical-session.target" ];
};

macOS#

Applied via programs.desktoppr in home/home.nix.

Changing the Wallpaper#

Replace wallpapers/wallpaper.jpg with your image (keep the same filename), or
Add a new image and update the wallpaper let-binding in home/programs/kde.nix
Rebuild: sudo nixos-rebuild switch --flake .#laptop

The service will apply the new wallpaper on next login (or you can restart it manually):

systemctl --user restart set-plasma-wallpaper.service

Recommended Format#

Format: JPG or PNG
Resolution: 1920×1080 or higher
