No - It is only required to control the second monitor.  The options vary with 
radeon versus radeonhd.

A secondary problem is sound card configuration.  In my case, the motherboard 
ALC883 is not configured.

Based on my research, I think this will be solved by udev rules.  I say this 
because different alsa options result in different video setups for the 
secondary monitor.  In one configuration I used xrandr --auto --- worked 
perfectly.  Now I have to use specific xrandr commands to get the desired 
results.  The radeon or radeonhd driver produce the same results.

I believe the only common link is the udev rules.

> I saw in your xorg.conf, that you used the option "HPD" "off". Is this 
necessary? If yes, does an Option "HPD" "swap" work also? You know that this 
should only be a temporal workaround, until the table in the driver gets 
updated and you don't need this option any more [1]. Please report the bug 
upstream, as I described above, if the option is necessary. Also I can do that 
for you, if you don't want to do that.

MAXCPUS=1. Ubuntu Intrepid installed, but i couldn't get any GUI. The x-server 
tried to start but failed. I also cannot switch to terminal using crtl-alt F1, 
because X keeps trying. sometimes i get the errormessage: no screens found. I 
tried ati, radeon, vesa, radeonhd. I tried installing the official ati-drivers. 
Nothing worked, then after hours of mindbreaking i installed Hardy Heron, IT 
worked! Installed the restricted drivers and the screen looks nice. No sound 
though and no wireless.

> How can i get Intrepid Ibex to work? I read somewhere that xorg 7.4 could be 
the problem or the 4GB of RAM. Don't know how to fix this though. Latest 
versions of Mandriva and OpenSuse also do not run from livecd or install and 
suse complains about the graphic card.
