       gtf - calculate VESA GTF mode lines


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


       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.


               Enable verbose printouts  This shows a trace for each step of the computation.

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

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