NAME

6       gtf - calculate VESA GTF mode lines

SYNOPSIS

10       [-x|--xorgmode]

DESCRIPTION

13       Gtf is a utility for calculating VESA GTF  modes.   Given  the  desired
14       horizontal  and  vertical  resolutions  and  refresh  rate (in Hz), the
15       parameters for a matching VESA GTF mode are printed  out.   Two  output
16       formats  are  supported:  mode lines suitable for the Xorg xorg.conf(5)
17       file, and mode parameters suitable for the Linux fbset(8) utility.

OPTIONS

21       -v|--verbose
22               Enable verbose printouts  This shows a trace for each  step  of
23               the computation.
24
25       -x|--xorgmode
26               Print  the  mode  parameters as Xorg-style mode lines.  This is
27               the default format.
28
29       -f|--fbset
30               Print the mode parameters in a format suitable for fbset(8).
