I've been doing some more testing on the Dell D420 referred to in #14.
If I boot with the 2nd monitor connected, the system starts with the displayed mirrored.
I can then use system / preferences / display to make the displays different.
If I unplug the monitor, I can use system / preferences / display to reset it back to a single display and it works.
If I then plug-in the monitor again, the display hangs in the same way as if the laptop was booted without a second display connected. Both primary and secondary screens are blank except for a stationary cursor on the secondary monitor.

If I switch to metacity as described in this thread, dual screens just work.
