If you are installing the X Window System, you can configure it during the kickstart installation by checking the Configure the X Window System option on the X Configuration window as shown in Figure 8-11. If this option is not chosen, the X configuration options will be disabled and the skipx option will be written to the kickstart file.
The first step in configuring X is to choose the default color depth and resolution. Select them from their respective pulldown menus. Be sure to specify a color depth and resolution that is compatible with the video card and monitor for the system.
If you are installing both the GNOME and KDE desktops, you must choose which desktop should be the default. If only one desktop is to be installed, be sure to choose it. Once the system is installed, users can choose which desktop they want to be their default. For more information about GNOME and KDE, refer to the Red Hat Linux Installation Guide and the Red Hat Linux Getting Started Guide.
Next, choose whether to start the X Window System when the system is booted. This option will start the system in runlevel 5 with the graphical login screen. After the system is installed, this can be changed by modifying the /etc/inittab configuration file.
Probe for video card is selected by default. Accept this default to have the installation program probe for the video card during installation. Probing works for most modern video cards. If this option is selected and the installation program cannot successfully probe the video card, the installation program will stop at the video card configuration screen. To continue the installation process, select your video card from the list and click Next.
Alternatively, you can select the video card from the list on the Video Card tab as shown in Figure 8-12. Specify the amount of video RAM the selected video card has from the Video Card RAM pulldown menu. These values are used by the installation program to configure the X Window System.
After configuring the video card, click on the Monitor tab as shown in Figure 8-13.
Probe for monitor is selected by default. Accept this default to have the installation program probe for the monitor during installation. Probing works for most modern monitors. If this option is selected and the installation program cannot successfully probe the monitor, the installation program will stop at the monitor configuration screen. To continue the installation process, select your monitor from the list and click Next.
Alternatively, you can select your monitor from the list. You can also specify the horizontal and vertical sync rates instead of selecting a specific monitor by checking the Specify hysnc and vsync instead of monitor option. This option is useful if the monitor for the system is not listed. Notice that when this option is enabled, the monitor list is disabled.
