Full desktop shell in WSL2 using WSLg (XWayland)

Note

If you want to use Wayland in WSLg in a simpler setup, you can try the WSLg (Wayland) tutorial.

In this tutorial, we will setup GUI in WSL2. No additional software outside WSL (like VcXsrv or GWSL) is required. You will find this tutorial very similar to the one that replaces Xorg with Xvnc. Indeed, it's pretty much the same tutorial, with some few changes.

The key component we need to install is the desktop metapackage you want (GNOME, KDE, Xfce, Budgie, etc), and after that, replace the default Xorg by a script that calls Xwayland instead.

For this setup, I will use Ubuntu 24.04, and install GNOME Desktop. Unfortunately older versions of Ubuntu lack some fundamental things, so we cannot reproduce it in older versions (at least not fully). Since the key components aren't bound to Ubuntu or GNOME, you can use your favorite distro and GUI. Check the [Sample screenshot

Installing KDE on WSL2

Inspiration: https://www.most-useful.com/kde-plasma-on-wsl.html

Setup

Update WSL
- In windows command prompt run: wsl --update
Add systemd to ubuntu

In ubuntu prompt run: sudo nano /etc/wsl.conf

After long searching I did not find a good description of how to set up Syncthing that works exclusively via CLI without using a Web browser on the devices.

This is useful for example on a headless Raspberry Pi without proxying web-traffic through SSH or with port-forwarding limitations. In this example we will want to share the default folder from Machine A with Machine B

Machine A	Machine B

Docker in Windows without Docker Desktop

❤️‍🔥 Install docker client in Windows

Download necessary version of docker binaries from https://docs.docker.com/engine/install/binaries/ and extract archive to c:/Program Files, for example, using script in powershell. Run powershell as Administrator and call:
```
Expand-Archive .\docker-20.10.9.zip -DestianationPath $Env:ProgramFiles  
```
Files docker.exe and dockerd.exe will be here c:/Program Files/docker/.

Get a DDNS up and running with DuckDNS - Step by Step

Understanding DDNS

In summary, DDNS stands for Dynamic DNS. DDNS updates a DNS name in real-time to point to a changing IP address. This is useful for devices without a static IP. For example, companies like Google use static IPs and IP ranges, which are more expensive than ephemeral IPs and IP ranges. DDNS provides a cost-effective alternative, linking a hostname to a dynamic IP address.

How Does DDNS Work?

To use DDNS, you need an account with a DDNS provider. While some services are paid, they are still cheaper than static public IPs from ISPs. A script or service on your device updates the DDNS server with your current IP at regular intervals to maintain the link between your hostname and IP address. Luckily for us, DuckDNS is free for everybody and relays on donations to keep their services running.
