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

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

Keychron Keyboards on Linux use the hid_apple driver (even in Windows/Android mode), both in Bluetooth and Wired modes. By default, this driver uses the F-keys as multimedia shortcuts and you have to press Fn + the key to get the usual F1 through F12 keys.

Hope this will stay relevant for longer than just 2021. This guide will focus mostly on things you shouldn't overlook and will harshly prioritise assuming that you're running on recent hardware. EFI and all that.

Always refer to the official guide in case of doubt.

First things first

One important thing first: the environment you will encounter on the live image is very different from what you'll end up installing, some things are significantly easier there: e.g. wifi tools come pre-installed, the default shell is a pimped zsh with nice completions, and so on. We'll keep this
