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.

Problem

I have a notebook connected to a port replicator. I want to use the build-in speakers and microfone and not the external ones. If I boot my notebook in my port replicator Ubuntu changes the devices to external.

Solution

Find your internal speaker

There are 28 static site generators that support AsciiDoc sourcing.

The PATH is an important concept when working on the command line. It's a list of directories that tell your operating system where to look for programs, so that you can just write script instead of /home/me/bin/script or C:\Users\Me\bin\script. But different operating systems have different ways to add a new directory to it:

Windows

The first step depends which version of Windows you're using:

If you're using Windows 8 or 10, press the Windows key, then search for and

I've used ->| to indicate a tab character, as it's clearer to read than ⇥
