Your laptop is known as a hybrid machine with two GPUs. The internal
display (and typically VGA) is connected to the weaker integrated GPU,
whereas the HDMI is connected to the discrete GPU. We are only just
beginning to catch up with Windows in enabling multi-GPU / multi-head
configurations - in the meantime you have to either make a choice about
which GPU to use, or to use something like bumblebee.
Note that in raring, we have the initial enabling of multi-GPU support.

Title:
[arrandale] Lenovo U460 HDMI doesn't work
Status in “xserver-xorg-video-intel” package in Ubuntu:
Invalid
Bug description:
Binary package hint: xorg
New Lenovo U460 laptop dual-booting with factory-installed Windows 7
(64 bit). When a monitor is connected via HDMI under Windows, it works
fine. Under Lucid, nothing happens at all. xrandr reports only the
laptop display (ie "Screen 0").
