--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).
