Video Output Switcher Control | ||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | ||

|
||
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: | ||
