External VGA support on my laptop

Hi Jing,
Thanks for your interest in my problem.

You were *right,* I was not running aticonfig under super user. There was no
indication that I had to do it this way.
Anyway, I can confirm that the backup was indeed sucesssful.  So, that path
to /etc/X11/ is definitely not the problem.

I have just re-executed aticonfig as super user with the following poor
result ending in an abort...

johnfruh at eMachine:~$ sudo aticonfig --initial --input=/etc/X11/xorg.conf
[sudo] password for johnfruh:
Uninitialised file found, configuring.
Using /etc/X11/xorg.conf
Saved back-up to /etc/X11/xorg.conf.original-1
