       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).
