How to set up working X11 forwarding on WSL2

 This tutorial is about properly setting up WSL2 X11 forwarding on Windows and Linux distro


  1. Add the following to your ~/.bashrc:  
    export DISPLAY=$(awk '/nameserver / {print $2; exit}' /etc/resolv.conf 2>/dev/null):0
export LIBGL_ALWAYS_INDIRECT=1
  2. Enable Public Access on your X11 server for Windows.*
  3. Add a separate inbound rule for TCP port 6000 to the windows firewall in order to allow WSL access to the X server, as described by the wsl-windows-toolbar-launcher people.
On the Ubuntu Wiki page about WSL you can already find a configuration adapted for WSL2 under Running Graphical Applications. A similar configuration is also suggested by the above mentioned Reddit User, who also contributes another part of the solution: Enable Public Access on the X11 server under Windows.
