4 Best Automatic Wallpaper Changer For Ubuntu 18.04

Last updated: July 14, 2018

Looking for how to create desktop slideshow in Ubuntu 18.04? Here I’ll show you some best wallpaper changing software for Ubuntu Linux.

1. Shotwell

For just the basic automatic wallpaper changing feature, you don’t need to install any software.

Just launch the pre-installed Shotwell photo manager, choose the pictures you need (you may need to import them first), then go to Files -> Set as Desktop Slideshow.

Finally set the time interval in next dialog and done!

2. Wallch

Wallch was my favorite wallpaper changing software though it’s not under active development. Besides changing local wallpapers, Wallch also features:

  • Display live earth as desktop background.
  • Download and display picture of the day (wikipedia).
  • Wallpaper clocks
  • Live website as desktop background.

Wallch can be easily installed in Ubuntu Software:

3. Variety

Variety is an open-source wallpaper changer that 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 can be easily installed in Ubuntu Software. For the latest release, go to Variety website.

4. Wallpaper Downloader

This is a wallpaper downloading software that automatically downloads pictures from Devianart, Bing daily wallpaper, Wallhaven.cc, etc., with given keywords, resolution, time interval. And of course, it provides ability to change wallpaper every x minute.

Wallpaper Downloader can be installed easily in Ubuntu Software.

These are the applications that I’ve ever used to create desktop slideshows in Ubuntu desktop.

If you know any other great wallpaper changing software, feel free to tell me in the comment.
