If more than one desktop environment is installed on your system
(for example, KDE and GNOME, or KDE 3.5.x
and KDE 4), you can choose to switch to another desktop when logging
in again (or when logging in as a different user). To do so, proceed
as follows:
On the login screen, click
and select the desktop environment to start.Enter a valid username and password. A new session on the selected desktop environment starts.
To switch back again, log out from the current desktop and select a different
on the login screen. If you do not select a new session type, your next session will be of the same type as the session before.
