Display brightness Fn keys on HP EliteBook 8730w

[Darko Veberic]

Binary package hint: hal-info

On HP EliteBook 8730w (with DreamColor LED LCD and nVidia G94M [Quadro FX 2700M]) the Fn+F9/F10 brightness keys open the brightness-change gnome indicator but don't do anything. The ambient-light switch Fn+F11 works properly.

in hal-info file /usr/share/hal/fdi/information/10freedesktop/10-laptop-panel-hardware.fdi this notebook needs to have the "laptop_panel.brightness_in_hardware" set to "false".

after the modifications above, my whole <match> tag in ubuntu lucid looks like:

<match key="/org/freedesktop/Hal/devices/computer:system.hardware.vendor" string="Hewlett-Packard">
        <match key="/org/freedesktop/Hal/devices/computer:system.hardware.product" contains_outof="2510p;2710p;nc2400">
          <merge key="laptop_panel.brightness_in_hardware" type="bool">true</merge>
        </match>
        <match key="/org/freedesktop/Hal/devices/computer:system.hardware.product" contains_outof="4410s;4415s;4416s;Compaq 5X5;HP EliteBook 8730w">
          <!-- needed since the acpi video module reports it handle the events, but it don't work on this machines-->
          <merge key="laptop_panel.brightness_in_hardware" type="bool">false</merge>
        </match>
      </match>

note the appended string ";HP EliteBook 8730w" in the second sub-match.
