<doc:para>
org.freedesktop.UPower.KbdBacklight is a DBus interface implemented
by UPower.
It allows the keyboard backlight (if present) to be controlled.
The object path "/org/freedesktop/UPower/KbdBacklight" is going to be deprecated in the future.
The new object path is based on this, but the suffix of the path is the device name.
For example:
The interface is: org.freedesktop.UPower.KbdBacklight
The object path will be: /org/freedesktop/UPower/KbdBacklight/tpacpiookbd_backlight
