Unfortunately, on a Dell Lattitude E6420 the behavior is not resolved; booting while docked results in an inability to bring display up on any/all monitors (including laptop internal display). Booting with laptop lid open results in docked monitors displaying correctly. After booting, closing laptop lid results in DPMI turning on for all monitors (including docked).

As a curious detail if I close the lid right after switching on the laptop, before Ubuntu starts up, it works as expected. Of course, I have set the Energy configuration to do nothing on closing the lid, and I agree that the laptop screen in that situation should go black, but not the external screen. There is a similar bug filled against previous versions of Ubuntu (#416236) that was considered a regression, but in that case there was a workaround using gconf-editor to manually edit the settings for the gnome-power-manager, but there is no such a entry now in 12.04.
