GTF(1)                                 General Commands Manual                                GTF(1)

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).
