+ MacBook brightness adjustment does not work in Hardy
** Description changed:
Binary package hint: hal
adjusting the brightness doesn't work. a brightness feedback widget
appears but is empty, and brightness remains at 100%. This is true
whether using the keys, or plugging in/unplugging a/c power.
+ Affected hardware: MacBook, MacBook Pro
+
+ As a workaround, install the pommed package, which manages screen
+ brightness, volume, etc. for MacBook independently of GPM and GSD.
