NAME
       gtf - calculate VESA GTF mode lines

SYNOPSIS
       gtf h-resolution v-resolution refresh [-v|--verbose] [-f|--fbmode] [-x|--xorgmode]

DESCRIPTION
       Gtf  is a utility for calculating VESA GTF modes.  Given the desired horizontal and verti-
       cal resolutions and refresh rate (in Hz), the parameters for a matching VESA GTF mode  are
       printed	out.   Two  output  formats  are  supported:  mode  lines  suitable  for the Xorg
       xorg.conf(5) file, and mode parameters suitable for the Linux fbset(8) utility.

OPTIONS
       -v|--verbose
	       Enable verbose printouts  This shows a trace for each step of the computation.

       -x|--xorgmode
	       Print the mode parameters as Xorg-style mode lines.  This is the default format.

       -f|--fbset
	       Print the mode parameters in a format suitable for fbset(8).
