I have two graphics cards, one is an NVIDIA GeForce 6200 128MB AGP, and the other card is an NVIDIA GeForce FX 5500 256 MB PCI

Right now, they are set to Seperate X Screens, and they seem to work independantly of each other, almost as if i'm on two seperate computers. How would I go about making them work like in Windows, where you can just drag from one to the other?

Second. I had Emerald installed, and when I enabled the second screen, my windows are left borderless, (With Compiz Fusion running) so I uninstalled Emerald, and started MetaCity and then tried to reload Compiz, I'm still borderless!
What do I do?

So, basically, I want to have Compiz Fusion with Emerald working right, as well as two seperate screens, that don't act like two seperate computers.
