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


       dumpreg < /dev/ttyN


       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


       svgalib(7),  vgagl(7),  libvga.config(5), vga_dumpregs(3), convfont(1),
       fix132x43(1),  restorefont(1),  restorepalette(1),  restoretextmode(1),
       runx(1), savetextmode(1), setmclk(1), textmode(1).

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

       Occasionally this might be wrong. I hereby asked to be excused  by  the
