Fedora Screensaver

To change your screensaver or screensaver settings click on System --- Preferences --- Look and Feel --- Screensaver

In the Screensaver Preferences window we see a list of available screensavers on the left side and a preview of the selected screensaver on the right. To see a more realistic preview click on the preview button beneath the list of available screensavers. We can also specify how long before the computer is regarded as idle and we can lock the screen when screensaver comes on. This means the user password will be required to continue.
