This chapter assists you in becoming familiar with the KDE desktop of your Linux system and in performing basic tasks.
KDE stands for K Desktop Environment and is a graphical user interface that has many applications designed to help you in your daily work. KDE also offers many choices to modify your desktop according to your needs and wishes. Read more about configuring your desktop in Kapitel 2, Customizing Your Settings.
The following description is based on the default configuration of the KDE desktop shipped with your product. If you or your system administrator has modified the defaults, some aspects may be different, such as appearance or keyboard shortcuts.
If more than one user account is configured on your computer, usually all users must authenticate—unless Auto Login is configured for a certain user. Auto login logs the user in to the desktop environment automatically on boot. Enable or disable this feature during installation or at any time using the YaST user management module. For more information, see Abschnitt „Benutzerkonten verwalten“ (Kapitel 5, Verwalten von Benutzern mit YaST, ↑Start).But if your computer is run in a network environment and you are not the only person using the machine, you are usually prompted to enter your username and password when you start your system. If you did not set up your system and your user account yourself, check with your system administrator for your username and password.
The program managing the login process depends on the desktop environment installed on your system. For KDE, it is KDM. If the GNOME desktop is additionally installed on your system, it may be GDM.
As shown in Abbildung 1.1, „A KDM Login Screen“, the default KDM login screen provides input fields for username and password and the following menu items:
Specifies the desktop to run when you log in. If desktops other than KDE are installed, they appear in the list. Make changes only if you want to use a session type other than your default (usually KDE). Future sessions are automatically of the same type unless you change the session type manually.
Performs a system action, such as shutting down the computer or starting different login actions.enables you to log in on a remote machine.
To start a normal login, just enter your username and password.
|Connecting to an Active Directory Server|
To access shared network resources, you can also authenticate a KDE client machine against an Active Directory server. For further details, refer to Kapitel 8, Accessing Network Resources. If your machine is configured for this kind of authentication, the login screen also provides an additional field. In this case, proceed as follows during login:
The Session Manager starts after your username and password are authenticated by the login process. The Session Manager lets you save certain settings for each session. It also lets you save the state of your most recent session and return to that state the next time you log in.
The Session Manager can save and restore the following settings:
Appearance and behavior settings, such as fonts, colors, and mouse settings.
Applications that you were running, such as a file manager or OpenOffice.org.
|Saving and Restoring Applications|
You cannot save and restore applications that Session Manager does not manage. For example, if you start the vi editor from the command line in a terminal window, Session Manager cannot restore your editing session.
For information about configuring session preferences, see Adjusting the Session Handling.
