I get exactly the same problem in an HP dv3 with a fresh-installed Natty. I'm using the proprietary driver from ATI (v11.4) with unity and compiz running. I have radeon and intel_ips modules blacklisted. When I connect the external VGA monitor it goes to login screen and, if I do login, I get two black screens with a frozen mouse pointer in the middle of both. Booting up with the monitor already plugged in yields the same scenario. Occasionally, I can see a stack trace blinking on and off both monitors. I'll try to get a photo of it. I also tried booting with recovery's failsafe mode and setup xorg.conf for a dual-head with "$ aticonfig --initial=dual-head -f", but it didn't solve it :(
