Gnome, KDE and XFCE users will have no problem changing the wallpaper on their desktop. However, if you are using a lightweight desktop manager such Openbox or Fluxbox, you will find that there is no way that you can set the wallpaper for your desktop. In this case, Nitrogen will come in handy.
Nitrogen is a simple, lightweight application that allows you to change the background of your desktop. Some of its key features include support for Multihead and Xinerama, a recall mode that can remember the last wallpaper set and command line mode for script use.
