I've built a rig with 3 7950s, running on ubuntu 12.04 bootable USB. Finally got cgminer working, and running one card at ~650khash/s (LTC)

For some reason ./cgminer -n shows all three cards are detected but when I start up, only one of them will run. Has anyone else had this issue, and how did you resolve it?

Thanks

Does anyone think that dummy plugs might help? I thought they were only necessary for windows but I guess I should try everything...
