Enable Function Keys On The Keychron K2 and K3 Mechanical Keyboard Under Linux

Below, you’ll find the steps required to create a systemd command that will run at boot to disable the media keys and restore f1-f12 functionality.

Open a terminal window and create a new file in the folder /etc/systemd/system/
File should be named keychron.service

sudo nvim /etc/systemd/system/keychron.service

Paste the following code into the window:

[Unit] Description=The command to make the Keychron K2-K4 work with Function keys [Service] Type=oneshot SyslogIdentifier=keychron ExecStart=/bin/bash -c "sudo echo 0 | sudo tee /sys/module/hid_apple/parameters/fnmode" RemainAfterExit=true Restart=on-failure RestartSec=10s [Install] WantedBy=multi-user.target 

To exit nvim press escape then : then w q and enter .

In the terminal, in order to enable the service type the following:

sudo systemctl enable keychron

To see the changes right away run last command:

sudo systemctl start keychron

If you want to simply drag/drop the file that you create manually in the steps provided, I have it under the scripts folder in this repo. Download it and drop it in /etc/systemd/system/ , doing Step 3 at the end.

README.md

Update : December 15th, 2022

This repository was originally named after the Keychron K2 keyboard, but after multiple other keyboards were reported to work, I decided to make the name more generic.

To be clear, this solution will not work without systemd ; a crontab could work as well if you don’t have systemd .

If you confirm that your keyboard works with this script as expected, create a ticket and I’ll add it to the list of user-tested keyboards. Alternatively, submit a PR with a modification to this readme.

Enable Function Keys On Keychron/Various Mechanical Keyboards Under Linux, with systemd

(or, disable pesky media keys)

Below, you’ll find the steps required to create a systemd command that will run at boot to disable the media keys and restore f1-f12 functionality.

Open a terminal window and enter the following command:

# Set the EDITOR variable with EDITOR=nano, uncommenting the line directly below # EDITOR=nano sudoedit /etc/systemd/system/keychron.service

Paste the following into the window:

[Unit] Description=Disable media keys and substitute in function keys [Service] Type=simple RemainAfterExit=yes ExecStart=/bin/bash -c "echo 0 > /sys/module/hid_apple/parameters/fnmode" ExecStop=/bin/bash -c "echo 1 > /sys/module/hid_apple/parameters/fnmode" [Install] WantedBy=multi-user.target

Press ctrl+o and then ctrl+x to exit.

In the terminal, type the following:

systemctl enable keychron

That’s it! A reboot, and you’ll see that the function keys have been re-enabled. Alternatively, run this command to see the changes right away: systemctl start keychron

If you want to simply drag/drop the file that you create manually in the steps provided, I have it under the scripts folder in this repo. Download it and drop it in /etc/systemd/system/ , doing Step 3 at the end.

On Linux, the Keychron K2 doesn’t register any of the F1-F12 function keys as actual F keys, instead, treating them as multimedia keys by default.

This section of the document describe how to change the behavior of ‘fn’ key to better match what user expect.

Here a description of each behavior :

• 0 = disabled : Disable the ‘fn’ key. Pressing ‘fn’+’F8’ will behave like you only press ‘F8’
• 1 = fkeyslast : Function keys are used as last key. Pressing ‘F8’ key will act as a special key. Pressing ‘fn’+’F8’ will behave like a F8.
• 2 = fkeysfirst : Function keys are used as first key. Pressing ‘F8’ key will behave like a F8. Pressing ‘fn’+’F8’ will act as special key (play/pause).

• Set the keyboard to Windows mode via the side switch
• Use Fn + X + L (hold for 4 seconds) to set the function key row to «Function» mode.
• echo 2 | sudo tee /sys/module/hid_apple/parameters/fnmode
• Optionally, reboot sudo reboot

Once complete, my F1-F12 keys work properly, and holding Fn turns them into multimedia keys. You can use the evtest utility to check how keyboard keys are registering until you get the above combination of settings configured properly.

To persist this change, add a module option for hid_apple :

echo "options hid_apple fnmode=2" | sudo tee -a /etc/modprobe.d/hid_apple.conf

You may need to rebuild your initramfs if hid_apple is included.

sudo update-initramfs -u -k all

To (re-)load the module for immediate use, run

sudo modprobe -r hid_apple; sudo modprobe hid_apple
