      6The output sysfs class driver provides an abstract video output layer that
      7can be used to hook platform specific methods to enable/disable video output
      8device through common sysfs interface. For example, on my IBM ThinkPad T42
      9laptop, The ACPI video driver registered its output devices and read/write
     10method for 'state' with output sysfs class. The user interface under sysfs is::
