The Structure

The /etc/X11/xorg.conf file is comprised of many different sections which address specific aspects of the system hardware.

Each section begins with a Article "<section-name>" line (where <section-name> is the title for the section) and ends with an EndArticle line. Each section contains lines that include option names and one or more option values. These are sometimes enclosed in double quotes (").

Lines beginning with a hash mark (#) are not read by the X server and are used for human-readable comments.

Some options within the /etc/X11/xorg.conf file accept a boolean switch which turns the feature on or off. Acceptable boolean values are:

• 1, on, true, or yes - Turns the option on.

• 0, off, false, or no - Turns the option off.

The following are some of the more important sections in the order in which they appear in a typical /etc/X11/xorg.conf file. More detailed information about the X server configuration file can be found in the xorg.conf man page.
