.SH DESCRIPTION
|
||
|
|
.I 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
|
||
|
|
.BR xorg.conf (5)
|
||
|
|
file, and mode parameters suitable for the Linux
|
||
|
|
.BR fbset (8)
|
||
|
|
utility.
