Video Output Switcher Control
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
2006 luming.yu@intel.com
The output sysfs class driver provides an abstract video output layer that
can be used to hook platform specific methods to enable/disable video output
device through common sysfs interface. For example, on my IBM ThinkPad T42
laptop, The ACPI video driver registered its output devices and read/write
method for 'state' with output sysfs class. The user interface under sysfs is:
linux:/sys/class/video_output # tree .

Note: display switching code is currently considered EXPERIMENTAL,
toying with these values may even lock your machine.
All settings are changed via /proc/acpi/asus directory entries. Owner
and group for these entries can be set with asus_uid and asus_gid
parameters.
More information and a userspace daemon for handling the extra buttons
at <http://sourceforge.net/projects/acpi4asus/>.
If you have an ACPI-compatible ASUS laptop, say Y or M here. This
driver is still under development, so if your laptop is unsupported or
something works not quite as expected, please use the mailing list
