   2 .SH NAME
   3 gtf - calculate VESA GTF mode lines
   4 .SH SYNOPSIS
   5 .B gtf
   6 .I h-resolution
   7 .I v-resolution
   8 .I refresh
   9 .RB [ \-v | \-\-verbose ]

  11 .RB [ \-x | \-\-xorgmode ]
  12 .SH DESCRIPTION
  13 .I Gtf
  14 is a utility for calculating VESA GTF modes.  Given the desired
  15 horizontal and vertical resolutions and refresh rate (in Hz), the parameters
  16 for a matching VESA GTF mode are printed out.  Two output formats are
  17 supported: mode lines suitable for the Xorg
  18 .B xorg.conf(__filemansuffix__)
  19 file, and mode parameters suitable for the Linux
  20 .B fbset(8)
  21 utility.

  23 .SH OPTIONS
  24 .TP 8
  25 .BR \-v | \-\-verbose
  26 Enable verbose printouts  This shows a trace for each step of the
  27 computation.
  28 .TP 8
  29 .BR \-x | \-\-xorgmode
  30 Print the mode parameters as Xorg-style mode lines.  This is the
  31 default format.
  32 .TP 8
  33 .BR \-f | \-\-fbset
  34 Print the mode parameters in a format suitable for
  35 .BR fbset(8) .
