1 .TH GTF 1 @vendorversion@ 2 .SH NAME 3 gtf - calculate VESA GTF mode lines 4 .SH SYNOPSIS 5 .B gtf 6 .I h-resolution 7 .I v-resolution 8 .I refresh 9 .RB [ \-v | \-\-verbose ] 10 .RB [ \-f | \-\-fbmode ] 11 .RB [ \-x | \-\-xorgmode ] 12 .SH DESCRIPTION 13 .I Gtf 14 is a utility for calculating VESA GTF modes. Given the desired 15 horizontal and vertical resolutions and refresh rate (in Hz), the parameters 16 for a matching VESA GTF mode are printed out. Two output formats are 17 supported: mode lines suitable for the Xorg 18 .B xorg.conf(@filemansuffix@) 19 file, and mode parameters suitable for the Linux 20 .B fbset(8) 21 utility. 22 23 .SH OPTIONS 24 .TP 8 25 .BR \-v | \-\-verbose 26 Enable verbose printouts This shows a trace for each step of the 27 computation. 28 .TP 8 29 .BR \-x | \-\-xorgmode 30 Print the mode parameters as Xorg-style mode lines. This is the 31 default format. 32 .TP 8 33 .BR \-f | \-\-fbset 34 Print the mode parameters in a format suitable for 35 .BR fbset(8) . 36 .SH "SEE ALSO" 37 xorg.conf(@filemansuffix@), cvt(@appmansuffix@) 38 .SH AUTHOR 39 Andy Ritger. 40 .PP 41 This program is based on the Generalized Timing Formula (GTF(TM)) Standard 42 Version: 1.0, Revision: 1.0. The GTF Excel(TM) spreadsheet, a sample 43 (and the definitive) implementation of the GTF Timing Standard is 44 available at <ftp://ftp.vesa.org/pub/GTF/VTF_V1R1.xls>.
