Variety is an open-source wallpaper changer for Linux
Variety is packed with great features, yet slim and easy to use. It can use local images or automatically download wallpapers from Unsplash and other online sources, allows you to rotate them on a regular interval, and provides easy ways to separate the great images from the junk. Variety can also display wise and funny quotations or a nice digital clock on the desktop.
Variety has an optional slideshow/screensaver companion application, Variety Slideshow. It can be installed separately, but it integrates nicely with Variety.
Variety can be managed from its tray icon, which allows skipping to the next or going to the previous wallpaper, add image to favorites or move it to the trash, show a wallpaper history or show recently downloaded wallpapers. As a result, it’s best to use Variety with a tray / appindicator. If that’s not possible, you can access some of these features by right clicking on the variety icon in your taskbar.
