Re: [XFree86] No signal to external VGA port

[Dan Mergens <dan@xxxxxxxxxx>]

It's my understanding that you must start X and have your XF86Config 
configured for your external monitor PRIOR to running X. You cannot 
switch between the two after X is running. If someone knows different, 
I'd love to hear how they do it.

I have a shell script that copies the proper configuration at boot time 
depending on the number of ethernet cards (whether I'm docked or not). 
This works well. The following link contains the instructions I used 
(although I modified the script to csh since I don't understand the perl 
(or whatever) he used and case statements are on the way out).

The trick is to know the secret K55xxxx in the right rc.x directories 
that automagically get called at boot time.
