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).
