First check your OS version

## windows 11

Follow the instruction in the link below:
https://docs.microsoft.com/en-us/windows/wsl/tutorials/gui-apps
---
---
## windows 10: Use VNC server
1. Open wsl and run update before everything starts.

    sudo apt update

2. Install XFCE desktop environment on your ubuntu WSL.

    sudo apt install xfce4 xfce4-goodies

3. Install TightVNC.

    sudo apt install tightvncserver

4. Then launch VNC by typing:

    vncserver

After launching, you will be asked to set a password which is used to verify the identification during connecting.

==Note: password over 8 characters will be trimed to 8.==

Once you will be asked to enter a view-only password, chose n.
View-only mode gives users limited access such as no keyboard and mouse functionality.

When all set up, run:

    echo "startxfce4 &">~/.vnc/xstartup

Which will add ```startxfce4 &``` at the end of the file.
(OPTIONAL) Use ```sudo nano ~/.vnc/xstartup``` command to check the file is changed or not.

5. Your IP address and local address are required for connecting, use:

    ifconfig

and

    netstat -lntp

commands and note them down as marked in the following images.


6. Starting VNC in WSL is not as same as a regular Ubuntu machine, we need to use starting script to cover the work.
Run:

    nano ~/vncstart.sh

Then add the following contents in the file:

    #!/bin/bash
    vncserver -kill :1 > /dev/null 2>&1
    rm -f /tmp/.X1-lock
    rm -f /tmp/.X11-unix/X1
    vncserver :1 -geometry 1366x768

After save and close the file, run:

    chmod u+x ~/vncstart.sh

to give the execution rights.

---
Last, run:

    ./vncstart.sh


7. Install VNC Viewer on your PC

8. In VNC viewer, eneter the address in step 5, combine them with ```:``` and then press enter.

Enter the password you set in step 4.

9. Enjoy your WSL GUI!
