Having the same problem on a Dell M6400 in Ubuntu 11.04. The key combo worked for me on 10.10 (which was upgraded 9.10 -> 10.04 -> 10.10). Then I recently did a fresh install of 11.04 and the Fn+F8 combo does not work. The screen flickers as if it's trying to do something, but it never activates the external monitor. I have to manually enable the external monitor and disable the laptop's LCD in nvidia-settings, which is quite tedious in comparison.
