===Dual monitor===
ATI's driver sucks. Don't get an ATI card and the following is just useful when one's stuck with it. This gives me 2 screens where window can be dragged to each other. Compiz is also working (after removing .gconf and .gconfd). The only outstanding issue is video flickering during horizontal panning.
