i3wm: How can I switch Fn Keys on a Logitech K600 TV Keyboard?

  • 772

My System: Ubuntu 18.04 LTS (Updated)

Window Manager/Desktop Environment: i3WM

The Logitech K600 TV Keyboard works flawlessly in my Laptop for the majority of the tasks, the features of this keyboard are awesome as it has 3 dedicated keys which I use for switching between the computer (using wireless dongle) and 2 Samsung Galaxy Tab devices (bluetooth connected).

The problem

The 3 dedicated keys I mentioned before, are the same keys used for F1, F2 and F3 which I should trigger by pressing a key combination with the Fn key.

Expected solution

I would like to switch the usage of the dedicated keys in order to make them trigger the default F1, F2 and F3 keys *whith no need to use the Fn in a combination.

Please consider

  1. I am using i3WM, no desktop environment, no other window manager.
  2. A BIOS based solution will only work for the physical keyboard on the laptop, not for the wireless keyboard.
  3. I have requested Logitech's support via support ticket, and they guided me to this page: https://support.logi.com/hc/en-us/articles/360025297893 which provides a list of resources made for Windows or MacOS. There's no a Linux solution from the manufacturers.
  4. This question: How can I make the function keys the default on a Logitech K760 Bluetooh keyboard? has an answer but it is for a different model, whose solution does not work on my model.

If you need further information from my system, don't hesitate to drop a message.

  1. You can use solaar, which has a version in Ubuntu's universal repo.

    sudo apt install solaar

    Then, you run solaar, it has a nice GUI with instructions, once you connect a Logitech keyboard, it will show you a switch for de Fn key behavior.
