dumpreg(1)		      Svgalib User Manual		    dumpreg(1)

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	appli-
       cation 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 con-
       sole 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.

       original	documentation is unknown.

       It is very likely that both are at least	to some	extent are due to Harm
