Here is the best setup (I think so :D) for K-series Keychron keyboards on Linux.

Note: many newer Keychron keyboards use QMK as firmware and most tips here do not apply to them. Maybe the ones related to Bluetooth can be useful, but everything related to Apple's keyboard module (hid_apple) on Linux, won't work. As far as I know, all QMK-based boards use the hid_generic module instead. Examples of QMK-based boards are: Q, Q-Pro, V, K-Pro, etc.

Most of these commands have been tested on Ubuntu 20.04 and should also work on most Debian-based distributions. If a command happens not to work for you, take a look in the comment section.

Make Fn + F-keys work (NOT FOR QMK-BASED BOARDS)

Older Keychron keyboards (those not based on QMK) use the hid_apple driver on Linux, even in the Windows/Android mode, both in Bluetooth and Wired modes.

Programming

Plug in the cable, you need the LED to guide you
Pn + Left Ctrl to enter programming mode
Press the key that want to be programmed
Press the target key
Pn to apply
Pn + Left Ctrl to exit

It's possible to lose a key. Sometimes you need to backup it first.

How to create a LXD Container with your ssh key in it (and with ssh server in the container)

Create a brand new ed25519 key pair

ssh-keygen -o -a 100 -t ed25519

Get the pub key and put the result in your lxd default profile

cat ~/.ssh/ed25519.pub
lxc profile edit default
