Customizing the XF86Config File
The following sections provide information about customizing the XF86Config file for
various special configurations.
Configuring a System for Stereo
This section describes how to configure a system to display stereo images.
Stereo sync is supported only on systems using ImageSync boards.
Note: Simultaneously running stereo and full scene anti-aliasing can require more
graphics-card memory than is available, and thus may not always work correctly.
Note: Stereo may be enabled on either channel of a pipe, but may not be enabled on both
channels simultaneously.
1. Create a copy of the XF86Config file to be customized for stereo:
# cp /etc/X11/XF86Config /etc/X11/XF86Config.Stereo
2. Edit the XF86Config.Stereo file to include the following line at the end of each
“Device” section:
Option "Stereo" "1"
Option "StereoSyncEnable" "1"
(see the “Example “Device” Section for Stereo” on page 134).
3. Edit the new XF86Config.Stereo file to include the appropriate stereo modes in
the “Monitor” section:
a. Create an appropriate mode (see “Sample Stereo Mode Entries” on page 135).
b. Add that mode to the “Monitor” section of your XF86Config.Stereo file (see
the “Example “Monitor” Section for Stereo” on page 135).
Note: “Mode” and “Modeline” are two alternative formats used to present the same
information.
