I have noticed that if I remove /etc/X11/xorg.conf, a default xorg.conf
is used. That is what I think people mean that Ubuntu does not use
xorg.conf. It is true if one is thinking about /etc/X11/xorg.conf
specifically (*that* file doesn't need to to exists, so is not being
used), not true if on is thinking about the graphics on the display
(*some* xorg configuration must be used).

To get better a insight, try the following experiment:
1) With /etc/X11/xorg.conf, reboot the machine and check what you get in
2) Next, rename /etc/X11/xorg.conf to something else (to keep a backup)
so that there is no /etc/X11/xorg.conf anymore, and reboot the machine.
Check the xorg log again.

In the first case, one should find something like this in the logs:
(==) Using config file: "/etc/X11/xorg.conf"

and in the second case on should find a corresponding line in the log
file stating that the default log file is being used.
