                      Let us learn how to install screensavers using the Ubuntu Software Center.
                      Installing Screensaver Software

                      A screensaver is an image, animation or moving pattern that appears on your

                      computer screen when the system is not in use for a certain period but remains
                      switched on. It helps prevent screen damage caused by static images staying on
                      the screen for too long and also makes your desktop look attractive.

                      Screensavers can display various effects such as floating shapes, photos or digital
                      clocks. Some screensavers also offer password protection, adding an extra layer of

                      security when you are away from your computer.

                      Before applying a screensaver, you must first install it from the Ubuntu Software
                      Center. Once installed, you can select your favourite screensaver, set the time after
                      which it should appear and customize its appearance and behaviour as you like.
