Hi,
I am new to cgminer and as well as Ubuntu.
I was able to install both and worked with my 7970. Currently with 550 Mh/s (925/775).
But when I tried to add my old 6950 to my motherboard, it does not seem to work with cgminer. It only shows GPU0 which is the 7970 card.
I am not sure if I did it right, is there a setting for the card combination?
Thanks.
Looks like you have not configured the second card as I see no mention of you having done in a terminal window
sudo aticonfig -f --initial --adapter=all then rebooting so the new dual card xorg.conf file will be used.
