Public bug reported:

I have a brand-new wireless Apple wireless keyboard, connected using
Bluetooth.

Some of the f-keys on this keyboard apparently have additional functions:
F1: decrease brightness
F2: increase brightness
F3: ?
F4: ?
F7: previous track
F8: play/pause
F9: next track
F10: mute
F11: decrease volume
F12: increase volume

In addition, https://help.ubuntu.com/community/AppleKeyboard indicates
that Insert, Delete, PageUp, PageDown, Home and End should be available
through using 'fn' with other keys.

None of these appear to work. Pressing 'fn' with any other key is
identical to pressing that key on its own. Using 'xev' confirms this.

I also notice that the kernel module hid_apple is not loaded when my
keyboard is connected.

There seem to be other bug reports (e.g. bug #227501, bug #499013) which
report new versions of Apple peripherals having new device IDs, which
prevent Ubuntu from configuring them properly when they are connected.
In some cases the fix seems to be a custom kernel (!) or kernel patch. I
don't know if this is the issue here. Please let me know what additional
information or testing I can provide to help fix this bug.
