I have 2 nVidia GeForce GTS 450/PCIe/SSE2 graphics cards, each with a DVI, VGA and HDMI port.
Unfortunately, only one of these cards is detected by Ubuntu, so I have to have one screen on VGA and the other on DVI. I'd like both to be DVI.
I am using Ubuntu 14.04 GNOME, fully updated. It never worked with 12.04 unity or 14.04 unity.
I am happy to edit in any information (but I have no idea what is needed right now).
