Turn on/off verbose output. FYI -q stands for quiet ;)
Turn on/off fbset (Linux framebuffer timings) mode. In this mode
fbset timings are printed instead of Modelines.
Turn on/off non-free NVidia Linux driver compatibility mode.
filespec as the configuration file. This accepts
- to read the options from the standard input. The "~" character
gets expanded to the home directory of the user running videogen.
|Adds modespec to the list of modes to calculate a Modeline for. This must be in the form 800x600 (width x height) and it can be specified more than once to add several modes.|
|Set freq to the maximum dot clock rate of your video card or the bandwidth of your monitor, whichever is lower, in MHz.|
|Set freq to the maximum horizontal refresh frequency of your monitor in kHz.|
|Set freq to the maximum vertical refresh frequency of your monitor in Hz.|
|Set freq to the vertical refresh frequency which you think it would be optimal for you, in Hz. The program will try to match this frequency at all resolutions, instead of the maximum frequency that would be technically possible. (optional)|
|Set percent to the percentage of the horizontal frame length you want the visible resolution to be. (optional)|
|Set percent to the percentage of the vertical frame length you want the visible resolution to be. (optional)|
|Set duration to the horizontal front porch duration of your monitor in clock ticks. (optional)|
|Set duration to the horizontal back porch duration of your monitor in clock ticks. (optional)|
|Set duration to the minimum horizontal sync pulse duration of your monitor. (optional)|
|Set duration to the vertical front porch duration of your monitor in clock ticks. (optional)|
|Set duration to the vertical back porch duration of your monitor in clock ticks. (optional)|
|Set duration to the minimum vertical sync pulse duration of your monitor. (optional)|
You can expect the following error codes to be returned by videogen:
100 system error (memory allocation problems, or other) 101 command line option error 102 configuration file error 103 bad resolution error, currently returned when no (valid) modes have been specified anywhere 104 bad maximum dot clock rate, currently returned when a proper value has not been specified anywhere 105 bad maximum horizontal refresh, currently returned when a proper value has not been specified anywhere 106 bad maximum vertical refresh, currently returned when a proper value has not been specified anywhere
If your display adapter does not have a programmable clockchip then you will need to get a list of available clocks somehow and enter these as the maximum dot clock frequency. This way videogen will have to adjust (decrease) the horizontal refresh frequency to get exactly the given dot clock rate. A similar method can be used to match the proper frequencies of a fixed frequency monitor.
~/.videogen This is the default location for the videogen configuration file. /usr/X11/lib/X11/XF86Config This is the common Xserver configuration file where the Modelines generated with videogen can be used. Currently this must be done by hand.
