When you are finished using the computer, you can log out and leave the system running or restart or shut down the computer. If your system provides power management, you can also suspend the computer, making the next system start much faster than a complete boot.
To log out and leave the system running, do one of the following:
From the main menu select +.
Use the keyboard shortcut that is defined in the Control Center Section 6.2.7, “Regional & Accessibility”. Usually, this is Ctrl-Alt-Del. Then click .
Click the icon in the panel. If your panel does not include the logout icon, you can add it to the panel as described in Section 5.1.3, “Locking Your Screen”.
