Configuration utility for setting up function keys on ubuntu for Logitech k480 keyboard.
Inspiration came from this place:

Mario made this tool for k810, I simply re-traced his steps for k480. My current configuration is Ubuntu 14.10 with k480 connected through some old d-link bluetooth adapter (on a desktop machine). Steps: check which hidraw device is your logitech keyboard:
$cat /sys/class/hidraw/hidraw*/device/uevent
Identify which one it is, e.g. hidraw2. Then run (after downloading files from here) $./build.sh $sudo ./k480_conf -d /dev/hidraw2 -f on
to make function keys behave as function keys by default. You can also revert this behaviour by running:
$sudo ./k480_conf -d /dev/hidraw2 -f off
which will make media keys default and function keys accessible by (fn + function key).
