Re: [XFree86] No signal to external VGA port

The way I have enabled my laptop setup is to switch XF86Config files on startup. The following is a helpful link for doing that:

I can live without hotkeying. My Problem is the never working CRT in X. Maybe I have a problem in understanding the XF86Config:


I define my LCD in a monitor section
I define my CRT in a 2nd monitor section

I define my Chipset in a device section

I define how to use the monitors connected to the device in a screen section
(both monitors in one section? maybe, because they must use same color depth. On the other hand XFree claims about trying to use the device twice, if I define two screen sections)


Now to enable them:
The 'man XF86Config' in 'DEVICE SECTION' says:
      Screen  number
             This option is mandatory for cards where a single PCI entity can
             drive more than one display (i.e., multiple CRTCs sharing a sin-
             gle  graphics accelerator and video memory).  One Device section
             is required for each head, and this parameter  determines  which
             head  each  of the Device sections applies to.  The legal values
             of number range from 0 to one less  than  the  total  number  of
             heads  per entity.  Most drivers require that the primary screen
             (0) be present.
Looks good, this seems to be my case.

My first question is:
Has the name 'Screen' in this part something to do with the 'screen section', or is it simply the same word for two different things?


The last sentence in the man page seems to be true for my driver. "Screen 1" results in:
"Device(s) detected, but none matches those in the config file."
"No screens found"
The same happenes, if I define 'Screen 0' and 'Screen 1' in the device section. At this point I get totally lost. Does this mean, the nv driver is not able to enable the lines to the external VGA port?


Please tell me, where I think wrong.

I played a bit around with:


Option "CrtcNumber" "0"
Option "FlatPanel" "0"


and modified the parameters, but I had no luck with it. Is there any documentation? The man page says nothing about this.

Thanks for help

Hi,

I have a Medion MD6100 notebook running SuSE Linux 8.2 XFree 4.3.0 (V
11.0) NVidia GeForce4 388 Go graphic chip.

The notebook has an external VGA port. I can switch internal / external /
both by keyboard (FN-F3). This works on console, but not in X. In X,
there is a signal on the VGA port, which causes my monitor to stay "on",
but it is black all the time. The function key works in X. It switches
the LCD display off, when I select 'external'.

Can I have my external VGA port working in X as well?

regards
Wolfgang
