Understood.

That seems to be true for Xorg, but not for XFree86 4.3, as I said in my
report, my setup worked with XFree86 4.3. I think it made the monitor
use a 1600x1050 resolution, which doesn't work with X.org

What I want to have is running my Laptop-Screen and my CRT-Monitor with
their heighest resolution together in a Xinerama-Setup using the
vertical size of my Laptop display (1050) and the width of double the
laptop-display (1680). This seems to be _not_ possible with X.org, as
X.org lets the CRT-Monitor not run with 1600x1200.

I can of course change the virtual desktop to be 3320x1200, but then I
have to scroll on my Laptop screen which is not very nice. I just
thought that the old Xfree-Setup should still work, if there is no way
you are free to close this bug.
