Comment 3 for bug 194609

There appears to be an issue with HAL or something with Gnome in Hardy that is perventing this and other key actions to be caught by Gnome. This works fine under Gutsy .. but is not getting picked up by Gnome in Hardy. The same goes for the FN+F3 (battery button), it is picked up in Gutsy and the little battery in the notification bar will display info on your battery, but under Hardy this is not happening. I checked gnome-power-manager source code and this functionality has not been removed from the battery. So this points me to something in HAL or somewhere.

Never the less this should go ahead and be included as it does work (just not under Hardy .. because of something in gnome)
