NAME
s3switch - manage the output devices on an S3 Savage chip
SYNOPSIS
s3switch [-q] [crt] [lcd] [tv] [both] [ntscj|ntsc|pal]
DESCRIPTION
The S3 Savage chips have the ability to send their output to a variety
of different devices. The Savage3D can display to a standard CRT or to
a TV. The Savage4 and Savage2000 can display to a standard CRT or
through a digital interface to an LCD panel. The Savage/MX and
Savage/IX can ship to any two of those three.
The s3switch utility is used to select the devices to be used, and the
format of the TV signal. When invoked with no parameters, s3switch
displays the devices currently attached, and which of those devices are
currently active. Supplying one or more of the words crt, lcd, or tv
makes those devices the active devices. The word both is a shortcut
for the combination of crt and lcd.
To change the format of the TV signal, specify either ntscj, ntsc or
pal. These words will be silently ignored on systems where a TV is not
attached or not possible.
The case of the keywords is unimportant; LCD and lcd are equivalent.
S3switch always displays the current state of things just before it
exits, unless the -q option is given, in which case, it operates
quietly. Note that only the Savage4 and Savage2000 are able to detect
the presence or absence of the various devices; the rest just assume
everything is attached. S3switch must be run as root.
S3switch will not allow you to activate devices which are not
connected, on those chips that are able to detect this.
