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).
