I have installed Linux Mint 14 KDE and I have two monitors which I would like to operate as one screen.
I have installed the nvidia driver for the graphics card but I cannot find how to use the nvidia software to control the screens.
I managed to get two screens working as one, but the background is plain black and the menu bar is top left rather than at the bottom. I can find no way to move it back to the original position.
How do I get a different background for the screen and access to the nvidia software?
