WSL2 DISPLAY xserver
TL;DR
add this line to your ~/.bashrc file (in the WSL2 machine)
export DISPLAY="$(cat /etc/resolv.conf | grep -Po "nameserver \K[0-9.]+"):0"
And install VcXsrv in your windows machine
Windows host IP
The windows host ip can be found by running
cat /etc/resolv.conf
This gives something like
# This file was automatically generated by WSL. To stop automatic generation of this file, add the following entry to /etc/wsl.conf: # [network] # generateResolvConf = false nameserver 172.20.112.1
Now, to programmatically get this ip we run
cat /etc/resolv.conf | grep -Po "nameserver \K[0-9.]+"
