NAME
gtf - calculate VESA GTF mode lines
SYNOPSIS
/usr/bin/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(4) 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).
