I'm running Ubuntu 9.04 (Jaunty), and I have a nVidia 8600GTS graphics card. I'm trying to get one monitor to work in portrait mode, and the other one in landscape mode. I know how to do this under Windows, but I can't find the setting for this under Linux. I've managed to get them both in portrait, or both in landscape, but not independant of each other.
I'd like to be able to switch modes for a single monitor without restarting the computer or X, but I realise that might be a bit too much too ask.
