This chapter introduces the GNOME (GNU Network Object Model Environment) desktop. It provides a brief overview of the most important elements and functionalities of your desktop, including an in-depth description of the Nautilus file manager. It also introduces several smart and useful applications that can help you feel at home in your new desktop environment. For information about configuring your desktop, see Chapter 8, Customizing Your GNOME Desktop.
If more than one user account is configured on your computer, all users must authenticate. When you start your system, you are prompted to enter your username and password. This is the username and password you created when you installed your system. If you did not install your system, check with your system administrator for your username and password.
If your computer is not run in a networking environment and you are the only person using it, you can automatically boot into the desktop environment. In this case, you do not see a login screen. This feature, called auto login, can be enabled or disabled during installation or at any time using the YaST user management module.
The program managing the login process depends on the desktop environment installed on your system. For GNOME, it is GDM. The login screen has the following items:
Enter your username and password to log in.
Specify the language to use in your session.
Specify the desktop to run. If other desktops are installed, they appear in the list. Make changes only if you want to use a session type other than your default (usually GNOME). Future sessions are automatically of the same type unless you change the session type manually.
Restarts the computer.
Shuts down the computer.
After your username and password are authenticated, the Session Manager starts. 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 session 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.
