Evening everyone,
I'm currently running kubuntu and a radeon 4870 (using the proprietary drivers) and I am trying to get my desktop to span multiple monitors, currently it is only allowing me to mirror on kde.

I've tried changing the settings in the system settings -> display -> multiple monitors, but it only tells me its only available for configuring systems with a single desktop spanning multiple monitors. (which coincidently is exactly what I want...)

So My question is how do I enable this? I have it set up in gnome no problem, but I like KDE more as a desktop environment and this is the only thing really holding me back from switching.
