Vesa modes

Introduction

I use the Xorg server with vesa driver to obtain the full list of vesa modes supported by the card. Parsing the /var/log/Xorg.0.log with the following quick and dirty perl script outputs the tables provided below in wiki style. Note that if you wish to use the vesa modes provided below in the kernel boot command with the vesafb driver you need to add 0x200 to it.

#!/usr/bin/perl -w

my $resolution;
my $bpp;
my $vesamode;
my $curline;

printf STDOUT ("{| border=\"1\" cellpadding=\"2\"\n");
printf STDOUT ("!width=\"75\"|Resolution\n");
printf STDOUT ("!width=\"50\"|Bits per pixel\n");
printf STDOUT ("!width=\"50\"|Vesa mode\n");
printf STDOUT ("|-\n");
while ($curline=<>)
{
  if ( $curline =~ /Mode: ([0-9a-f]+) \(([0-9]+x[0-9]+)\).*$/s )
  {
    $vesamode=$1;
    $resolution=$2;
  }
  if ( $curline =~ /BitsPerPixel: ([0-9]+)$/s )
  {
    $bpp=$1;
#    printf STDOUT ("vesamode %s for resolution %s at %s bpp\n",$vesamode,$resolution,$bpp);
    printf STDOUT ("| %s || %s || %s\n",$resolution,$bpp,$vesamode);
    printf STDOUT ("|-\n");
  }
}
printf STDOUT ("|}\n");

The goal of this excercie is to seek for modes to be used on LCD TVs.
