GTF(1)

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(@filemansuffix@) 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).
