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  sup-
      ported:  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).
