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).
