NAME

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

SYNOPSIS

11       dumpreg < /dev/ttyN

DESCRIPTION

15       The chipset drivers of svgalib inquire the mode  of  the  graphic  card
16       when  the application is started and restore it when the svgalib appli‐
17       cation quits.  dumpreg prints this information to stdout.
18
19       This is useful for debugging or adding modes to a  device  driver.  For
20       example  you  can  use  Xfree86  to setup a given mode timing, then run
21       dumpreg and use it's stdout to make your  chipset  driver  use  exactly
22       this timing.
23
24       However,  the recent change of svgalib to hunt an own free virtual con‐
25       sole does not allow this,  because  it  will  make  Xfree86  return  to
26       textmode  first. You can avoid this by using the second form where N is
27       the number of the virtual console on which Xfree86 runs (usually 7)  as
28       root.
