To change some system-wide settings, you need to use YaST instead. This is the case for administrator settings (including most of the hardware, the graphical user interface, Internet access, security settings, user administration, software installation and system updates and information). For information about using YaST, refer to the integrated YaST help texts or to the Book “Start-Up.

To access the GNOME settings dialog, right-click the desktop and choose Settings.
