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 hor-
       izontal and vertical resolutions and refresh rate (in Hz),  the  parame-
       ters  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).
