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).
