Matt, surely I tried already to google. I used different setups if found. I
also tried the setups users in #ubuntu are using. I also tried to setup my
own xorg.conf. I also tried many times to run fglrxconfig with different
parameters. Everything with no success.

The best behavior I reached was a running second display with the need to
restart my X after my second display is connected. This is very, very
unhandy if you sit in the meeting and you need to show something, which
itself takes only 5 minutes. But the restart itself needs at least the same
time (stop my VMWare, stop my OpenOffice, stop anything others, restart X,
restart the needed Apps...)

I only want a clone mode of my display. My LCD has a resolution of 1600x1200
and the external displays (mostly a projector has only 1024x768).

I am trying to solve this issue nearly one month now. The most time I spent
in the IRC to get the support. 

But maybe you could help, if you know plenty of people, I am nearly at the
place there I am giving up...

As I have already written, I tried it in the meanwhile many different
solution. For now I do not have any further ideas. I am not a Xorg / fglrx
specialist. I am a simple, stupid user...

I am not complaining generally that Ubuntu doesn't do anything for me, but
if Ubuntu wants to reach the desktops, simple tasks as connecting the
projector shouldn't be so hard, that it is not solvable by a simple setup.
Maybe there is an xorg.conf setup helper, but I do not know any. I expected
it, that it is part of the Ubuntu-distri.

I am using Ubuntu already as a server system for various environments. I
hoped I can run Ubuntu as my desktop replacement for WinXP, but it is harder
as I hoped.

Anyway here is my setup:
