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 KDE control center. Usually, to log out with confirmation, this is Strg-Alt-Entf. In the following dialog you still have the choice to cancel the logout process. If you want to log out without any confirmation, press Strg-Alt-Umschalttaste-Entf.
Click theicon in the panel.
