14.3. Installing and Configuring Fonts
14.4. OpenGL—3D Configuration


The X Window System (X11) is the de facto standard for graphical user interfaces in UNIX. X is network-based, enabling applications started on one host to be displayed on another host connected over any kind of network (LAN or Internet). This chapter describes the setup and optimization of the X Window System environment, provides background information about the use of fonts in SUSE Linux, and explains the configuration of OpenGL and 3D.

The following text contains several references to documentation that can be found below /usr/share/doc/packages/Xorg and /usr/share/doc/howto/en. This material along with respective manual pages is available only if the appropriate documentation packages are installed (xorg-x11-doc, xorg-x11-man, and howtoenh).

14.1. X11 Setup with SaX2

The graphical user interface, or X server, handles the communication between hardware and software. Desktops, like KDE and GNOME, and the wide variety of window managers, use the X server for interaction with the user. The graphical user interface is initially configured during installation. To change the settings afterwards, use the respective module from the YaST control center or run SaX2 manually from the command line with the command sax2. The SaX2 main window provides a common interface for the individual modules from the YaST control center.
