There are several ways to log out of, or end, your Kubuntu session. Use one of
these procedures if you wish to switch users, shutdown or reboot your system.
Right-click on an empty area of your Kubuntu Desktop and
choose (where “user”
represents your username).
You may also click on The K Menu icon in the Toolbar
and choose .
Either of the log out methods described above will result in the End Session
Screen.
Choosing End Current Session will quit your Kubuntu session
and return you to the “login” screen where you can switch users and
start a new session, reboot or shutdown. Choosing Turn Off
Computer will shutdown and power-off your system. Clicking on
Restart Computer will reboot.
