 Plugged PS/2 keyboard  into mouse port.

You can add the following lines to: /etc/modprobe.d/hid_apple.conf

$ cat /etc/modprobe.d/hid_apple.conf
options hid_apple fnmode=2
options hid_apple iso_layout=0

Then run sudo update-initramfs -u -k all and sudo reboot

 

mac_hid or hid_apple

 Turns out hid_apple was renamed to applespi.

echo 2 | sudo tee /sys/module/applespi/parameters/fnmode

For trackpads and laptop keyboard
