How to switch/disable functionality of fn keys on Ubuntu - USB keyboard
this is the best solution what i found ;-)
I found a software solution.
clone the following program from github:
git clone https://github.com/lentinj/tp-compact-keyboard.git
compile to following program:
cd tp-compact-keyboard/tp-compact-usb-keyboard
make
sudo ./tp-compact-usb-keyboard /dev/hidraw1
Maybe some errors are shown when you execute the program.
This program sent 2 keystrokes to the keyboard (0x05 and 0x01).
i think, you can't press them physically:

They are mapped to special keys.
this is only a temporary solution - after a reboot this settings are gone.
maybe you create a cronjob to fix it permanently:
