DesktopNova is an Ubuntu wallpaper rotator which switches the desktop background after a set time interval. This is quite similar to the Windows 7 style wallpaper rotation feature. DesktopNova is similar to the previously reviewed Desktop Drapes, however, it has more options and primarily relies on a daemon to rotate the wallpapers. Wallpapers can be specified either by selecting a folder or individual images.
You can install DesktopNova in Ubuntu by entering the the following commands in the Terminal:
sudo apt-get install desktopnova desktopnova-module-gnome sudo add-apt-repository ppa:michael-astrapi/ppa sudo apt-get update sudo apt-get install indicator-desktopnova
Once DesktopNova is installed, you can launch it from the Unity Dash and configure settings. To add wallpaper images for rotation, head over to the Images tab and add source file(s) or folder(s). You can select wallpaper rotation time limit from the Settings tab. Make sure you click on Start Daemon from Settings to ensure that the Daemon is running for wallpaper rotation. Similarly, mouse wheel switching and system tray session can be enabled from the Tray-icon tab, whereas, a file extension filter can be created from the Advanced tab.
For the Daemon to work, you will require selecting at least one module, click on Modules from Settings and select a module before starting the daemon.
Once the daemon starts, wallpaper rotation will automatically start according to your set time interval.
You can switch to the next or previous wallpaper or change preferences from the system tray menu.
DesktopNova can also be compiled for Debian, Fedora and OpenSuse from the package given at Launchpad.
