Hello, Joe,
The server doesn't start; stderr shows the following (captured with
"xterm 2> test.log"
This is regardless of the setting of "UseFBDev"
Following this is the generated xorg.conf. I see a strange "modeline"
entry for 720x400 --
could that be the problem? I believe that in the past I've deleted
this and even tried to replace
it with a 1024x768 line, but truthfully I can't remember any more.
David

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.

Okay, this looks good. You are using the correct framebuffer driver
(the
ATI Radeon driver and not the OpenFirmware FB driver, which won't work
for X) and it appears that your monitor is correctly responding with
an
EDID for autodetection. Can you try generating an X config file with
xac
and give that a try? If it doesn't work out of the box, try
uncommenting
the "UseFBDev" option and try both "true" and "false", sometimes the
correct value is not autodetected by X.
