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 X.org Server Configuration

  

There are a variety of X.org 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 X.org Configuration

  

The main X.org 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 X.org 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.
