| 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 ] | |

| 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. | |

| 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) . | |
