** Description changed: The Primary (internal) display of my laptop is blank if an external display is connected when the laptop is started. The loader and Greeter will be shown the external display, and the extended desktop will be shown on the external monitor as expected. However, the Launcher is not visible, as it is located on the internal display. When this first occurred, I hot-plug disconnected the external display, to try and force the desktop onto the internal display. A fuzzy white grid pattern then started creeping in from the edges of the laptop display. To recover from the problem, the external display had to be reconnected, restoring the previous (incomplete) view of the extended desktop. Starting the laptop, with the external display not connected, the internal laptop display shows fine. Hot-plug connecting the display once the machine is booted also works as expected, allowing both displays to be used. This seems to be a regression in P (12.04 development branch), as this setup was previously working fine in Oneiric.
