I have two radeon 4650 card in a multi seat configuration. My first problem
was getting the second card to work. I did the following:

# turn on second card

if [ -e /sys/bus/pci/devices/0000\:02\:00.0/enable ]
then
        if [ `cat /sys/bus/pci/devices/0000\:02\:00.0/enable` == '0' ]
        then
                echo 1 > /sys/bus/pci/devices/0000\:02\:00.0/enable
                echo 1 > /sys/bus/pci/devices/0000\:02\:00.0/rom
        fi
fi

The second card now sort of works. The screen will start, but the picture is
not correct. For instance a diagonal line gets a large zig-zag. See these
pictures:

correct gdm screen on first monitor:

wrong gdm screen on second monitor:
http://jvfoto.mine.nu/half_p2011046.jpg

note the zig-zag arc, the flower being positioned of screen and strange
printing of the words "Welcome" and "Username".

If I use the fglrx driver on the second screen everything looks allright,
but I have other problems with that setup, for instance not being able to
restart the X-server.

I first tried the release version 1.2.4. Now I have tested the current git
version (2009-01-31) with the same results.

I have attached a tar file with:
Xorg.0.log for the first screen
Xorg.1.log for the second screen (wrong)
xorg.conf with the used configuration
and the two screenshots
Comment 1 Jeremy Huddleston Sequoia 2011-10-16 15:59:33 UTC
Does this issue occur with the preferred ati driver (xf86-vide-ati)?  If so, please move this to the Driver/Radeon component.  

Development of radeonhd has pretty much halted and development focus is on the ati driver.  Please see http://www.x.org/wiki/radeonhd

If the issue does not exist in the ati driver (or if there is no response to this message), this bug will be closed as WONTFIX unless someone contributes a patch.

I don't recall exactly. I think I was using the radeon driver at the time. I am now using the xf86-video-ati.
Comment 3 Jeremy Huddleston Sequoia 2011-10-23 21:56:10 UTC
Ok, closing assuming you mean that it isn't occuring with the ati driver...
