|
|
.SH NAME
|
|
dumpreg \- dump the state of the card as the svgalib chipset driver sees it.
|
|
.SH SYNOPSIS
|
|
|
|
.BI dumpreg
|
|
.br
|
|
.BI "dumpreg < /dev/tty" N
|
|
|
|
.SH DESCRIPTION
|
|
The chipset drivers of svgalib inquire the mode of the graphic card when the application
|
|
is started and restore it when the svgalib application quits.
|
|
.B dumpreg
|
|
prints this information to stdout.
|
|
|
|
This is useful for debugging or adding modes to a device driver. For example you can
|
|
use Xfree86 to setup a given mode timing, then run
|
|
.B dumpreg
|
|
and use it's stdout to make your chipset driver use exactly this timing.
|
|
|
|
However, the recent change of svgalib to hunt an own free virtual console does not allow
|
|
this, because it will make Xfree86 return to textmode first. You can avoid this by using
|
|
the second form where
|
|
.I N
|
|
is the number of the virtual console on which Xfree86 runs (usually 7) as root.
