Hello, Joe and JR:

Thank to both of you for your help; it took me until now to find the  
time to once again find time to
fiddle with this problem.

The symptom is that the monitor gives a message that there's no signal  
and goes away.  Terminating X
with some combination :-) of shift keys and the delete key brings back  
a text terminal.  A very lengthy log
file gets generated, but to the best of my ability I can not find any  
indication of an error in it.

Checked the FAQ, but I'm not clear how to "set the correct framebuffer  
device" -- or what that might mean.

Probably my blindness, if you can direct me I'll be grateful.


Here's the output from xac:

I get something a bit more laconic from Xorgautoconfig as follows:

dfminigentoo ~ # Xorgautoconfig --dump

JR, Thanks for the link and advice, but it didn't get me any further.   
I used to do this configuration quite a bit, but in recent years it  
hasn't been necessary.

David
