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	vertical  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).
