## System Menu

The System menu allows you to set your preferences for the GNOME Desktop, get help with using GNOME, and log out or shut down.

- The Administration submenu contains tools to manage your computer. These all require your system's password.

- The Preferences submenu contains all the preference tools. With these you can configure your GNOME Desktop. For more on preference tools, see Capitolo 8, Configuring Your Desktop.

- The Help item launches the Help Browser.

- The About GNOME item has a brief introduction to GNOME, links to the GNOME website, and credits.

- The Lock Screen command starts your screensaver, and requires your password to return to the desktop. For more on this, see la sezione chiamata “Blocco dello schermo”.

- Choose Log Out to log out of GNOME, or to switch user.

- Choose Shut Down to end your GNOME session and turn off your computer, or restart it.

For more on logging out and shutting down, see la sezione chiamata “Fine di una sessione”.
