S3switch
General
S3switch is a utility to switch between various output devices and formats supported by the S3 Savage chipsets.
This tool allows you to switch between the CRT, LCD, and S-Video (TV) output devices. The S-Video output device can be set to output as NTSC, NTSCJ or PAL TV signal format. S3switch can also output the current status and available output devices.
NOTE!
If you have Option "UseBIOS" "off" in your X Server configuration file, s3switch will only work when the X Server is not running.
