I tried upgrading driver for 5850 with Catalyst_9.12_Hotfix_Linux_8.682.2RC1_Dec15.zip ( I assume this is the driver I need for 2.0 SDK ) But when I add the second Screen (card) to ServerLayout section in xorgs.conf - X wont start, but hangs on a black screen with signal, but no picture. Not even the annoying "Testing use" watermark. Removing the second screen works fine, but only a single GPU is avialable. When X hangs on a black screen, it is possible to use both GPUs from a text consol I can even connect through x11vnc and averything seems to work normally until I move the mouse, at which point vnc only shows screen updates, but doesn't recieve more input.. X will also respond to CTRL - backspace when "hanging" This seems to be a regression from the 9.10 driver (8.661) where this setup actually worked.

My setup is:

Ubunty (jaunty) 2.6.28-17-generic

2 x HD5850 without CrossfireX connected

1 Monitor conected to the first card. (no monitors attached to the second)

My xorg.conf is attached. I don't need a second screen, just 2 GPUs, and preferably no watermark. Is there a newer driver I can use with SDK v2.0 - or do I have to revert to the old (fglrx_8.661) ? Please help...

I did some more debugging on this issue, and attached a monitor to the secondary card. To my surprise the secondary display works fine.

I have tried juggling the displays around in xorg.conf, and the result is always the same: Primary display is left blank, while the secondary works. Unfortunately I haven't been able to get a setup I can work with, since most windows will open on the primary display, which I can only reach with VNC.

Similar problem is reported here:

It seems that this a regression after 9.10 which did work (for me), as such it is purely a driver bug, and should be reported elsewhere. But where should I report it ?  tried using the feedback in the gaming section, but I couldn't report Linux bugs there.

I connected the crossfire, but I still cant get a single display with 2 GPUs. However I did catch this in dmesg:

Ahhh... the wonders of closed source drivers...
