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 suit-
       able 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).
