I'm connecting an Apple Bluetooth Aluminum keyboard (this one) to my Lubuntu setup using the blueman applet.

The keyboard types fine, but I would like to use its fn key to change screen brightness changing, page-up (fn+ctrl+down), page-down (fn+ctrl+up), et cetera. Right now the fn key doesn't seem to work.

When I use xev, I don't see anything happen when I press fn.

Does the keyboard not send this to the computer at all?

Do I need to configure blueman's "Input Service" setting to make this an Apple (rather than a generic) keyboard? (It's not obvious how to do this.)

Is xev just not showing the fn key?

Where in this stack of software do I need to make a change to achieve the desired behaviour?

Thanks!

Try using the program gnome-bluetooth. It can be installed through the software center. –  William Nov 29 '11 at 17:37
    
@William, I have installed it via sudo apt-get install gnome-bluetooth. It is unclear to me how to run it since calling gnome-bluetooth from the command line tells me the command is not found. –  Richard Nov 29 '11 at 17:43
    
@William, I found the applet under bluetooth-applet. Unfortunately, it didn't solve any of my problems. –  Richard Dec 2 '11 at 5:37
    
Okay, sorry I can't be of any more help. –  William Dec 2 '11 at 15:29
