Hi Alex,

Xorg doesn't segfault anymore. The fix looks very simple. Has anybody used more
than two screens with evergreen before? 

Now the card drives all screens (2xDVI + HDMI), but one has the same wrong
colors as I've seen without Xorg, which makes sense because of KMS. You pointed
out that I'll need a DP screen. Is it really necessary? Because the mouse
pointer is correctly drawn on every screen. Dmesg points out that the DP and
HDMI port share the same UNIPHY. Afaik it is possible to connect HDMI to DP and
DP will create a HDMI signal. Probably the HDMI port of this card is already
connected to the DP and I don't need a DP screen. If not, pls proof me wrong.
The broken screen is connected via DVI and it's the third connected screen. 

Now either the third screen should be deactivated because it is not possible to
drive it correctly or there's another bug if you connect more than two screens.
This leads back to my first question.
