Since version 1.3 of the xserver-xorg-core package the configuration file
xorg.conf has more flexibility for multi-head configuration. The different heads
(outputs) of the graphical unit can be bound to different monitor sections via
an option called "Monitor-<ouputname>" in the device section (compare man-page
xorg.conf(5): monitor section). Especially in notebooks, the LCD called LVDS
(compare /var/log/Xorg.0.log) is sometimes not bound to the monitor section (and
its settings) without this additional option in the device section. An example
configuration (for an intel graphic device but transferable to any hardware) can
be found on http://www.intellinuxgraphics.com/dualhead.html.

Interesting is also the output of the command xrandr to learn about the
available graphical outputs and to configure them.
