For some reason, Ubuntu does not include the screen saver option by default.  So, I like to add this option and the option to turn of my monitor after certain time.  Here is how to install it and run it.

1. By holding Ctrl+Alt+T you start a Terminal Window
2. type the following to remove gnome-screensaver:
• sudo apt-get remove gnome-screensaver
3. Now, Type the following to install the screen saver with extra screens
• sudo apt-get install xscreensaver xscreensaver-gl-extra xscreensaver-data-extra
4. You need to go to Control then find Startup Applications

5. Add the following to allow the Screen Saver to start on boot
• xscreensaver -nosplash
6. Now, you need to edit the configurations and you do this by going to Dash and typing xscreensaver
7. Enjoy, make sure you configure the Blank after, Cycle after, and the Advanced configurations.
