Configure Xming display on WSL2

Question

I'm trying to configure an Xming display on my WSL2, and after an amount of troubleshooting attempts, I'm quite clueless.

For details:

System: WSL2 on Windows10Pro
Xming: installed. Some hopefully relevant lines from log:

• Xming :0 -multiwindow -clipboard
• XdmcpRegisterConnection: newAddress 172.27.16.1
• Could not init font path element C:\Program Files (x86)\Xming/fonts/100dpi/, removing from list! (there are a few of these)
• winInitMultiWindowWM - DISPLAY=127.0.0.1:0.0
• winInitMultiWindowWM - XOpenDisplay () returned and successfully opened the display.
• winMultiWindowXMsgProc - XOpenDisplay () returned and successfully opened the display.
• winClipboardProc - XOpenDisplay () returned and successfully opened the display.

Firewall:

What I've tried: (on WSL2 terminal)

export DISPLAY=$(awk '/nameserver / {print $2; exit}' /etc/resolv.conf 2>/dev/null):0
export LIBGL_ALWAYS_INDIRECT=1

As shown here

export DISPLAY=$(grep -m 1 nameserver /etc/resolv.conf | awk '{print $2}'):0.0

As shown ni subsequent link here
export DISPLAY=172.27.16.1 (/:0/:0.0) as taken from the Xming log.

Results so far: in all cases I get

No protocol specified
Error: Can't open display: 172.27.16.1:0

or alike

Any advice?

Finally, a friend found a solution that worked for me. In short:

• use putty to open a WSL terminal and export DISPLAY variable as WORKSTATION_IP:0.0
• in Xlaunch, check the "No Access Control" box.

I've put this as instructions in layman's terms in this short doc
