Installation

1. Clone or download this repository (or just the script and config files).

2. Create configuration directory and file:

   mkdir -p ~/.config/wallpaper_switcher
   
   

3. Copy config.ini to ~/.config/wallpaper_switcher/ Adjust paths, filenames, monitor models, and interval as needed.

4. Save the script as set_wallpaper.sh somewhere, e.g. ~/.local/bin/set_wallpaper.sh

5. Make it executable:

   chmod +x ~/.local/bin/set_wallpaper.sh
   
   

6. Add to your hyprland.conf to run on startup:

   exec-once = ~/.local/bin/set_wallpaper.sh
   
   

Usage

Run the script manually or let Hyprland start it on launch. It will:

Start the swww daemon if it’s not already running.

Set the appropriate wallpaper on your laptop and external monitors.

Refresh wallpapers every check_interval seconds.

How it works

The script reads your config file for wallpaper paths, monitor models, and settings.

It uses hyprctl to find connected monitors matching your external monitor models.

Wallpapers are applied with swww img on each monitor.

Wallpapers change depending on the current hour:

Night: 22:00–06:00

Morning: 06:00–13:00

Afternoon: 13:00–22:00

Troubleshooting

Ensure swww is installed and in your PATH.

Check monitor model names exactly as they appear in hyprctl monitors.

Confirm your wallpaper paths and filenames are correct.

Run swww daemon manually if the script has issues starting it.
