1 Getting started with the GNOME desktop #
Learn about the default configurations of GNOME.
GNOME is an easy-to-use graphical interface that can be customized to meet your needs and personal preferences. This section describes the default configuration of GNOME. If you or your system administrator modify the defaults, certain aspects might be different, such as appearance or key combinations.
Certain versions of SUSE Linux Enterprise ship with as many as three different session configurations based on GNOME. These are GNOME, GNOME Classic, and SLE Classic. The version described here is the default configuration of SUSE Linux Enterprise Desktop, which is GNOME.
1.1 Logging in #
All users must authenticate—unless is enabled for a specific user. In this case, a particular user is logged in automatically when the system starts. This can save time, especially if a computer is used by a single person. It may impact account security. Auto Login can be enabled or disabled during installation or at any time using the YaST User and Group Management module. For more information, refer to Chapter 6, Managing users with YaST.
If your computer is running in a network environment and you are not the only person using the machine, you are usually prompted to enter your user name and password when you start the system. If you did not set up the system and user account yourself, check with your system administrator for your user name and password.
In the login screen, select your user name.
If your user name is not listed, click . Then enter your user name and click .
Enter your password and confirm with Enter.

- GNOME (default)
A GNOME 4 configuration that is close to the upstream design. It focuses on interrupting users as little as possible. However, starting applications and switching between them works differently from many other desktop operating systems. It uses a single panel at the top of the screen. This session is started on Wayland.
- GNOME Classic and GNOME Classic on Xorg
GNOME classic is for users who prefer a more traditional desktop experience. It is based on GNOME 4 technologies but provides a number of changes to the user interface.
- GNOME on Xorg
By default SUSE Linux Enterprise Desktop uses GNOME with Wayland. Choose this option to start GNOME on Xorg. This is also the version used in this documentation.
