Linux Function Keys
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. Here’s how to fix it!
To fix it:
Set the keyboard to Windows mode via the side switch and use the Fn + X + L shortcut to set the function key row to “Function” mode.
Run: echo 0 | sudo tee /sys/module/hid_apple/parameters/fnmode
Once complete, the F1-F12 keys should work properly, and holding Fn turns them into multimedia keys.
To persist this change:
Run this to add a module option for hid_apple:
echo "options hid_apple fnmode=0" | sudo tee -a /etc/modprobe.d/hid_apple.conf
For Ubuntu: sudo update-initramfs -u
For Arch: mkinitcpio -P
I hope this helps.
