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).
