Hello - I would like to use six monitors with my Ubuntu 14.04. I have a gtx 780 and a quadro K600 graphic cards. The gtx gives me outputs for four monitors and K600 for two more. Can I have the two graphic cards working together within the same machine and under the same diver? I have the gtx 780 already working well in the system, installing the K600 would be plug and play or would require more?
