I switched from 12.04 to 12.10 yesterday evening (fresh install). Now I'm struggling with my second monitor, which I can't configure.
In 12.04, after installing the system, I got a notice telling me that I'd need to install further graphic drivers. After doing so I had a nvidia control center where I was able to configure everything.
However, 12.10 didn't ask me about graphic drivers and there's also no nvidia-settings application installed. I can't see the second external monitor (connected via DVI), only the internal one and one of the external monitor (connected via VGA, both monitors are the same model).
I have a HP Elitebook 8530w with an nVidia graphics card (Quadro, I don't know where to show the exact type of the card). When booting, Ubuntu configures dual screen for one of the external monitor and the internal laptop monitor. But I somehow can't tell him to turn off the internal monitor and use the second external monitor instead.
