Use Function Keys without pressing the fn button in the mac keyboard?
The article there should help you.

I inserted these two echo lines into /etc/rc.local
:
echo 2 > /sys/module/hid_apple/parameters/fnmode
echo 2 > /sys/module/apple/parameters/fnmode
Those are inserted just before the "exit 0" line.
From the Ubuntu community wiki on Apple Keyboards... Open this file with root permissions in terminal:
gksudo gedit /etc/modprobe.d/hid_apple.conf
Then add to the end of the file:
options hid_apple fnmode=2
And then finally in terminal...
sudo update-initramfs -u
Reboot your computer.
This will change the default keys to being the Function keys, E.g F8 is F8 instead of Play/Pause song. Hope this helps! ^.^
