With Karmic Alpha 4:

Used the System -> Preferences -> Display app rather than xrandr
directly.

Turning off the laptop display and enabling the second screen with
1680x1050 resolution resulted in two black screens except for 10-20
lines of corrupt graphics on the top of the left screen (showing parts
of the top GNOME panel bar). The second screen was enabled  however, and
I was able to move the mouse cursor from the left to the right screen as
expected.

After the timeout, the old settings were restored and the left screen
worked as it did after booting.

I set Visual Effects to none under Preferences -> Appearance and tried
enabling second screen in the Display app again. This successfully
enabled both screens with 1680x1050 resolution.

By enabling visual effects again I could reproduce the two black screens
(but without any corrupt graphics this time). After disabling visual
effects it was again possible to successfully enable the second screen.
