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 .B XF86Config(__filemansuffix__) file, and mode parameters suitable for the Linux .B fbset(8) utility. .SH OPTIONS .TP 8 .BR \-v | \-\-verbose Enable verbose printouts This shows a trace for each step of the computation. .TP 8 .BR \-x | \-\-xf86mode Print the mode parameters as XFree86-style mode lines. This is the default format. .TP 8 .BR \-f | \-\-fbset Print the mode parameters in a format suitable for .BR fbset(8) . .SH "SEE ALSO" XF86Config(__filemansuffix__) .SH AUTHOR Andy Ritger. .PP This program is based on the Generalized Timing Formula (GTF(TM)) Standard Version: 1.0, Revsion: 1.0. The GTF Excel(TM) spreadsheet, a sample (and the definitive) implementation of the GTF Timing Standard is available at <ftp://ftp.vesa.org/pub/GTF/VTF_V1R1.xls>.
