RDP provides a remote desktop from Windows to WSL. The RDP client is run on Windows and displays the Linux desktop running in WSL.
Install the RDP server and the XFCE4 desktop:
sudo apt install -y xfce4 xrdp
Set XFCE4 as the default desktop:
echo xfce4-session >~/.xsession
If systemd is running the xrdp server will start automatically on install, but it needs a restart after modifying .xsession:
sudo service xrdp restart
Check if xrdp is running:
systemctl status xrdp
If xrdp is not running, start it:
sudo service xrdp start
Print and save the IP address of the WSL instance:
ifconfig
Install ifconfig if it is not installed:
sudo apt install net-tools -y
On Windows, start the remote desktop viewer, mstsc. It is also called Remote Desktop Connection on the Windows application menu.
Enter the IP address you saved in the box.
Click Yes that you really want to connect.
Enter the Linux username and password for the WSL Linux distribution.
VNC can also be used for a virtual desktop.
Refer to VNC for details. The instructions work the same for WSL 2.
