How to setup VNC on Wayland (Sway) + SDDM for unattended access

1. Install both `x11vnc` and `wayvnc`

Since SDDM runs under X11 we will be running two separate vnc services, each on it's own port. x11vnc will take care of SDDM, while wayvnc will handle our desktop session. Both services are set up with SSL encryption.

While it's technically possible to run a single service with some scripting magic to switch between the two, this was by far the easiest and most reliable way.

2. Set up x11vnc

Enable PipeWire on Ubuntu 22.04

This guide is only for original Ubuntu out-of-the-box packages. If you have added a custom PPA like pipewire-debian, you might get into conflicts.

Ubuntu 22.04 has PipeWire partially installed and enabled as it's used by browsers (WebRTC) for recoding the screeen under Wayland. We can enable remaining parts and use PipeWire for audio and Bluetooth instead of PulseAudio.

Starting from WirePlumber version 0.4.8 automatic Bluetooth profile switching (e.g. switching from A2DP to HSP/HFP when an application needs microphone access) is supported. Jammy (22.04) repos provide exactly version 0.4.8. So, we're good.

Based on Debian Wiki, but simplified for Ubuntu 22.04.

NB: This document describles a 'Old-School' way of using Yubikey with SSH

Modern OpenSSH has native support for FIDO Authentication. Its much simpler and should also be more stable with less moving parts. OpenSSH also now has support for signing arbitary files witch can be used as replacement of gnupg. Git also supports signing commits/tags with ssh keys.

Pros of FIDO

Simpler stack / less moving parts
Works directly with ssh, ssh-add and ssh-keygen on most computers
Simpler
Private key can never leave the FIDO device

Cons of FIDO

Revert / Undo a Gist Commit

It was not exactly obvious. Here's how to revert a Gist commit!

Checkout the gist like a normal git repo:

# replace the Gist ID with your own
git clone [email protected]:cc13e0fcf2c348cc126f918e4a3917eb.git

Treat it like a normal repo. Edit, force push, etc.

	#!/bin/bash -e

	# Define variables
	USER_NAME="user"
	RDP_PORT=3389
	# Create a new password for the RDP user
	USER_PASSWORD=$(< /dev/urandom tr -dc _A-Z-a-z-0-9 \| head -c${1:-12})

	# Check for root privileges
	if [[ $EUID -ne 0 ]]; then

	@ECHO off
	:top
	CLS
	ECHO Choose a shell:
	ECHO [1] cmd
	ECHO [2] bash
	ECHO [3] PowerShell
	ECHO [4] Python
	ECHO.
	ECHO [5] restart elevated
