Two-Minute Drill

Here are some of the key points from the certification objectives in Chapter 14.

X with Clients and Servers


The X server software manages the graphics display on the local computer, which includes your monitor/graphics adapter, keyboard, and mouse.


You can configure the X server during the installation process. You can also configure or modify the configuration using the Red Hat Display Settings tool.


The X server configuration is stored in the /etc/X11/xorg.conf file.

The Server Configuration


There are a variety of server configuration files in the /etc/X11 directory.


You can start X servers in multiple consoles.


You can configure the X Window to boot directly into a GUI login manager, or start it from a text console.


When you start the X Window, you can customize the process.

Tools for Configuration


The main Server Configuration utility is the Red Hat Display Settings tool, which you can start in either the GUI or a text console with the system-config-display command.


Other command line tools are available, such as Xorg -configure and Xorg -probeonly.

Running Remote X Applications


By default, X clients sends display output to the local computer.


You can log into the remote client using the Secure Shell; if you log in with the -X or -Y switch, you can send remote X clients back to your local system.

Desktops and Window Managers


The X Window System gives you a blank electronic canvas. The look and feel of a GUI is provided by the window manager and desktop.


The two main desktop environments are GNOME and KDE.


You can use switchdesk from a terminal window or the command line interface console to select your default desktop.
