A screensaver is a computer program used primarily for security. This program blanks the screen or fills it with moving images or patterns when the computer is not in use. A screensaver can also be used for entertainment or to display system status information. It is a very good solution while you plan to leave your office and don’t want anybody to see what you working on.
How does a screensaver makes my computer secure?
A screensaver can be configured to ask users for a password before permitting the user to resume work, but be careful because if you have set set your account to automatically log in upon startup the attacker will be able to access your account simply by restarting the machine.
How to install a screensaver?
Fire up a new terminal like shown in Figure 1.
Before installing a new screensaver we have to remove the default one. Run the ‘sudo apt-get remove gnome-screensaver’ command shown in Figure 2 to uninstall gnome-screensaver.
