Editing the Linux* OS Configuration File Directly

Instead of using CED, as described in Platform Configuration Using CED, you can edit the xorg.conf file directly. The following procedure outlines the steps to follow when editing the Linux* configuration file. The Linux* OS Configuration File provides details on each section of the configuration file.

1. Log in as root and open the configuration file for editing. The configuration file is typically located in the /etc/X11 directory but may be located elsewhere on your system.

2. In the Device section of the configuration file, enter the appropriate information for your driver. The configuration file must have at least one Device section. The Device section lets you define information about Intel^® EMGD. You can use a single Device section for single or clone configurations. For Dual Independent Head configurations, you must specify a second Device section.

3. In the Screen section, enter information for each display in your configuration. The configuration file must have at least one Screen section. The Screen section binds a Device with a Monitor and lets you define resolution modes for the display. The Screen section is referenced in the ServerLayout section of the configuration file.

4. In the Monitor section, define monitor specifications and timings that will be used for the display. You must have a Monitor section defined for each display in your configuration. The Monitor section is referenced by the Screen section.

5. Save your changes to the file. For systems booted to run level 3, startx to restart. For systems booted to run level 5, kill X (Ctrl-Alt-Backspace) to restart. Reboot if necessary.
