Enable Function Keys On The Keychron K2 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.
Step 1
Open a terminal window and enter the following command:
sudo nano /etc/systemd/system/keychron.service
Step 2
Paste the following into the window:
[Unit]
Description=The command to make the Keychron K2 work
[Service]
Type=oneshot
ExecStart=/bin/bash -c "echo 0 > /sys/module/hid_apple/parameters/fnmode"
[Install]
WantedBy=multi-user.target
Press ctrl+o
and then ctrl+x
to exit.
Step 3
In the terminal, type the following:
systemctl enable keychron
Step 4
That's it! A reboot, and you'll see that the function keys have been re-enabled.
Closing Remarks
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.
