cipz / gnome_wallpaper_carousel

Process that changes desktop background automatically for Gnome Linux distros.

Gnome3 automatic wallpaper carousel

This simple program is being developed with the idea of making a daemon that could change the wallpaper automatically.

Usage

Configuration

The main file in this repo is carousel.sh. The config.json file only contains the directory of the wallpapers.

crontab

In order to make this script run automatically a cron job must be set up.

There are a lot tutorials online, but in a nutshell:

1. Run crontab -e -u your_username
2. Add a new rule like */10 * * * * /path/to/repo/carousel.sh >/dev/null 2>&1
3. Save and exit

This rule executes the script once every 10 minutes. For more detailed information about crontab timing go check out this (amazing and simple) website.

Clone the repo in the bin folder or in the folders you keep for custom scripts so that you don't have it laying around.

It is important that all files do not contain any spaces.

gsettings

In this stackoverflow answer it's explained why gsettings does not play well with cron and crontab.

The latest iteration of this script keeps in consideration the picture-uri-dark option in gsettings in Ubuntu 22.04.
