NAME

       dumpreg - dump the state of the card as the svgalib chipset driver sees it.

SYNOPSIS

       dumpreg
       dumpreg < /dev/ttyN

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.  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 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 N is the
       number of the virtual console on which Xfree86 runs (usually 7) as root.
