Is your desktop screen going dark or showing a blank screen when idled? By default, Ubuntu is developed with screensaver enabled. It is automatically activated when your computer becomes idled for roughly 5 minutes. When watching movies or online flash videos and the screensaver is activated, it darkens your display. If this is becoming a problem and you want to turn it off, then this brief tutorial is going to show you a single line command that will turn if off for you.

On a personal note screen savers SHOULD NOT BE ON BY DEFAULT.
How do we undo these changes?
Lets say after a movie, we use our computers for the general purposes where it is beneficial to have black screen coming when the system is idle.
How do we then restore the default settings?
