Description of problem:
I have a ati-radeon-7000 card with dualhead capabilities. When
configuring it with s-c-d everything is accepted, but after restarting 
X, nothing has changed. I have the same output on both displays.
The xorg.conf produced by s-c-d seems correct (is attached).

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. starting s-c-d 
2. giving the correct hardware data (radeon,dualhead,monitors etc)
3. restarting xorg


Actual Results:  nothing has changed

Expected Results:  a dualhead configuration with a spanned desktop

Additional info:

I had dualhead working with debian unstable and debians dri-enabled
xserver from Michael Daenzer.

booting without rhgb makes no difference ...
Comment 5 Sven Kromminga 2005-01-02 07:34:10 EST
Changing cable from bnc to d-sub solves the bug ...
X needs ddc to detect the second monitor (see log). 
Still strange: the first mon works without ddc using a bnc cable which
offers a much better quality with my monitors.
