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
(search for LVDS in /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.
Although its an example for a dual-head configuration, it makes clear the
principle of the new option "Monitor-<ouputname>".
