randomWallpaperD

Dynamically sets per-monitor wallpapers and changes them on a 30 minute timer. Running as a daemon, this script supports monitor hotplugging by polling the window manager for active outputs, then intelligently assigns random wallpapers per-screen with swaybg.

Arguments

If called without arguments, it assumes wallpapers are in a directory ~/.local/share/backgrounds. The first argument can be used to set the directory:

./script.rb ~/path/to/my/wallpapers

Window Manager Support

Because this script polls the window manager directly by way of its CLI utility, it currently only supports Hyprland (with hyprctl) and Sway (with swaymsg).
