Public bug reported:

Binary package hint: xserver-xorg-video-intel

The 13" MacBook Pro (8,1) has an integrated Intel 3000 video card. As of
Ubuntu Natty Narwhal 64bit+mac Nightly 2011.04.16, whenever I attempt to
connect an external display using the supplied VGA adapter, the external
display is properly detected by vendor, resolution and refresh rate.
However, the screen is black and it claims that there is no input
source. I can drag windows into that region, but the display is just not
showing anything.

You can see this behavior clearly by disabling compiz (Ubuntu classic,
no effects). When compiz is enabled, you get additional problems. As
soon as the display is recognized, the primary screen goes black. The
only way to restore the primary screen is to disconnect the adapter,
switch to the virtual terminal and restart gdm (sudo service gdm
restart). Clearly compiz is interfering with the monitor detection
process.

Here are two references to threads further describing this issue:
