WSL2 with GUI using Xvnc

Note

If you want to use pure WSLg, you can try the new WSLg tutorial.

In this tutorial, we will setup GUI in WSL2, and access it using VNC. No additional software outside WSL (like VcXsrv) is required, except, of course, a VNC Viewer (RealVNC, TightVNC, TigerVNC, UVNC, etc, all of them might work flawlessly).

The key component we need to install is the desktop metapackage you want (GNOME, KDE, Xfce, Budgie, etc) and tigervnc-standalone-server.

For this setup, I will use Ubuntu (20.04, 22.04 and 24.04 are working), and install GNOME Desktop. Since the key components aren't bound to Ubuntu or GNOME, you can use your favorite distro and GUI. Check the Sample screenshots section for examples.
