The best I've been able to do is to actually use the Ubuntu config  file, which at least displays on the digital monitor.  Tweaking the  config (changing PCI address, changing driver to vesa) switches the output  from DVI to VGA, but I cannot get both displayed at the same time.  I'd  love to have an extended desktop.

On 27-11-2007 I posted a message on this subject with a solution. You'll 
find the information below. However, not being able to get a better 
resolution on the second monitor, I stopped trying to get it right, it 
simply took me too much time. Maybe you can find out more.
NB. Since I have a graphics card from ATI, I don know what driver will 
work for you.

Earlier message:
===
Dual head: I got it working also by using the right items in 
/etc/X11/xorg.conf after installing the necessary driver by the command:
yum install kmod-fglrx (This is for the ATI card)

My copy of xorg.conf is:

===============

The desktop is stretched now over the two monitors, which was my aim. 
The only thing still bothering me is the resolution of the second 
monitor: 800x600, even though 1024x768 is mentioned in xorg.conf.

Hope this helps
