I am trying to run XFCE Desktop Environment for Ubuntu 20.04 in WSL (not WSL2, fyi. My laptop does not support virtualisation).
I have installed xrdp, xfce4 and xubuntu-desktop using sudo apt install <package-name>.
I have also rechecked, and even restarted the xrdp service using sudo service xrdp status and sudo service xrdp restart. The service does seem to be running.
But upon trying to connect to the Remote Desktop using Remote Desktop Connection(mstsc), it establishes a connection, seems to confirm that the authentication is correct and simply closes (no desktop is shown).
Here's the log from xrdp.log

I have tried connecting using 127.0.0.1 as well as 172.20.10.2, both which yield same result.
I have also tried editing the /etc/xrdp/startwm.sh like I saw in the Internet (Commenting out the last two lines and adding startxfce4). It doesn't seem to be making any difference.
P.S Please do not recommend solutions of using XLaunch, XMing or such similar local Xserver apps. Those do work succesfully, but I am choosing to go for RDP for specific reasons.
Thanks in advance.
I solved the issue by uncommenting the command
#exec /bin/sh /etc/X11/Xsession by opening file sudo nano /etc/xrdp/startwm.sh
