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).
This program is based on the Generalized Timing Formula (GTF(TM)) Standard
Version: 1.0, Revsion: 1.0. The GTF Excel(TM) spreadsheet, a sample
(and the definitive) implementation of the GTF Timing Standard is
available at <ftp://ftp.vesa.org/pub/GTF/VTF_V1R1.xls>.
