Ubuntu 13.04 - Dual-monitors - Primary Monitor: Black Screen, Secondary
Monitor: Unresponsive Desktop

So I recently installed Ubuntu 13.04 alongside Windows 7 and I'm loving it
so far. Everything is working fine except my second monitor.
If I'm already in Ubuntu when I plug the second monitor in, everything
works fine (Except for the limited resolution). But if I then reboot, my
primary monitor is completely black and the secondary monitor has the
desktop but is completely unresponsive.

Graphics Card: XFX Radeon HD 6850
Primary Monitor: DVI
Secondary Monitor: VGA
If you need any more information, please ask.
Thank you.
