Fix for the Lofree Flow keyboard Fn keys on Linux

The issue with the Lofree Flow keyboard is that it cannot recognize Linux system correctly. This causes Fn keys behave only like media keys. And it does not allow switching to the Fn mode (Fn + Lock).

This little script fixes this issue. In my case every time I switch off and switch on the Lofree Flow keyboard, it forgets the settings and I have to run it.

This script just changes the Fn mode directly in the keyboard parameters file: /sys/module/hid_apple/parameters/fnmode.

• Value 1 means Fn lock is off: default action of the F1, F2, ... keys is media control.
• Value 2 means Fn lock is on: default action of the function keys is a standard function key action (F1, F2...F12). And media control works by pressing Fn + F1, Fn + F2, and so on.

How to use

1. Download script file: wget https://raw.githubusercontent.com/alexeygumirov/lofree-flow-fn-fix/main/lofreemodefix
2. Make it executable chmod +x lofreemodefix.
3. Run it: ./lofreemodefix

Or just make your own script file with the same content:

#!/bin/sh

echo "Fixing Lofree Fn Mode"
echo
echo "Please swtich keyboard into the MacOS/iOS mode: Press Fn + M"
echo 
read -p "Press any key to continue... " PRESSKEY
echo
echo "Setting Lofree Fn Mode to 2"
sudo sh -c 'echo 2 > /sys/module/hid_apple/parameters/fnmode'
echo "Done!"
echo
echo "You can set keyboard back to Windows/Android mode by pressing Fn + N"

Make it executable and run it.
