Calculate vesa gtf mode lines
Usage
gtf h-resolution
v-resolution
refresh
[{-v | --verbose}]
[{-f | --fbmode}]
[{-x | --xf86mode}]
Overview
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 XFree86 XF86Config-4(5x) 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|--xf86mode-
Print the mode parameters as XFree86-style mode lines. This is the default format.
-f|--fbset-
Print the mode parameters in a format suitable for
fbset(8).
