What in plasma/fw5 monitors laptop function keys for backlight control?


  Plasma/fw5 key-stroke handler is properly monitoring the 'function-F9' and
'function-F10' keys for backlight control (brightness down/up). However, when
using the nvidia driver, the keystrokes are translated into updating the
following in sysfs:


instead of


  Setting the first (range 0-20) has no effect on backlight and must be
translated to a range of 0-127 for the nvidia setting. Where would I look in
the source code to find what is handling the brightness function keys?
kdelibs? kdebase?
