Starting a Graphical Environment session
By default, the Graphical Environment runs the scologin display manager on
the second of your console multiscreens (/dev/tty02).
This display manager starts the X server and keeps it
running on your system, even when a user is not engaged
in a Graphical Environment session.
However, you can choose to turn the scologin client off and start the X server manually, or you can run an additional server session on another multiscreen manually. To run the X server manually, run the startx script.
Regardless of the method you use to actually run the X server, a default Graphical Environment session is controlled by the session management client, scosession. scosession defines the clients that are run when you start the server and controls their appearance and behavior.

The above sections assume that you are using clients in their default configuration.
