I have an Asus laptop with a x1600 ATI Mobility Card.
My laptop backlight is broken so I can't really see anything on it, so I use a normal CRT monitor as output (the card has a VGA out).
With my old xorg.conf I get "cloning" (I see the same thing on both monitors) since I had not configured as dualmonitors.
Now I'm trying to do that (waiting to get the backlight fixed and would like to have this setup by then).
After some frankenstein-like configuration (mixed old one with something I found on the net) I came up with this:

X starts but since I can't actually check if it worked ok (can't see anything on laptop LCD) I used `xrandr -q`, and the output was
[ ~ ]-[$] > xrandr -q

Not much of an expert but I'm assuming both LCD and CRT monitors have the same resolution, and "cloning" is still present.
Please help me setup a proper dual monitor environment. What am I doing wrong here?

It does look like your still getting the same resolution there. This might not be the best solution but, I disconnected my laptops sreen after it broke, and it solved the similar problem i had.
Someone else might have a simpler solution though, if thats not your kind of thing.
