I'm running an nvidia card on a machine running a fresh install of 12.04. I'm using the drivers available from the main repos. I have the program 'nvidia-settings' available.
I have an x display on each monitor. However, when I switch desktops on one monitor, the desktop on the second monitor also changes.
This is a departure from the behaviour that I had on 10.10, where I could control each monitors desktop display independently.
Is there any way to get this behaviour back on 12.04?
