I gave that a shot. When I started up X, it gave me my good old
mirrored/cloned display.
I was confused about one part:

I don't see anything in the output (pasted below) that looks like
Monitor-VGA-0.

I think that part is out of date. Per
https://help.ubuntu.com/community/RadeonDriver
which is for ati video cards, you should be able to use any name you
want to for the monitors.

Here is another page on the community help wiki that might help:
https://help.ubuntu.com/community/Video
Basically, they refer you back to the ati page for dual head (dual
monitor), https://help.ubuntu.com/community/RadeonDriver#MergedFB
You may need to define 2 screens in the "ServerLayout" section. I only
see one screen defined now, which may be why they are clones.
good luck,

Charlie - thanks a ton for your help. Unfortunately, this is where I
just start to get confused - there are so many options. I don't know
which is best, which will work or which I'm using incorrectly.
As I understand it, I can choose to use either the proprietary driver
(fglrx - https://help.ubuntu.com/community/BinaryDriverHowto/ATI) or the
open source driver (ati - https://help.ubuntu.com/community/RadeonDriver)
As a note, I'm currently using the prop driver.
Then, from there I seem to have a couple of different options to try to
get dual-head support
Prop. Driver:
-xrandr: https://wiki.ubuntu.com/X/Config
-BigDesktop: http://ubuntuforums.org/showthread.php?p=1773544
Open Source driver:
-xrandr
-MergedFB: https://help.ubuntu.com/community/RadeonDriver#MergedFB or
http://ubuntuforums.org/showthread.php?p=1773710
So, I've tried the instructions for BigDesktop using the prop driver;
that hasn't worked.
I've tried the instructions for XRandR, and that hasn't worked.
I'd prefer to stick with the proprietary driver (as it scares me a bit
to have to go through the process of removing it, install the
open-source driver and then hope it works)

I don't have a good understanding of how X configuration works (who
really does... the documentation is intense), so I don't understand what
exactly it would do to put a second screen in the ServerLayout?
(should the documentation on https://wiki.ubuntu.com/X/Config be updated)

I feel like I'll need it.
