The simplest way to customize Ubuntu is to change the wallpaper. A good wallpaper changes the looks of the desktop drastically.
Changing desktop background in Ubuntu is just a matter of a right click. However I am writing this tutorial to share a few behind-the-scene tips and information which you might miss or never know even after using Ubuntu for years.
If you are using Ubuntu with the default GNOME desktop you should find a dedicated background option in the system settings.
Press the WindowsSuper key and look for Settings or background.
Go to the Background tab and you8217ll see a bunch of wallpapers. These are the default Ubuntu wallpapers that come pre-installed with the operating system.
The current wallpaper is displayed at the top. You8217ll also notice that some wallpapers have a clock icon. These wallpapers change throughout the day at a regular time interval. I8217ll explain about them later in this article.
