Ive got black screen when tried connect to linux from Windows Remote Desktop Connection. Solution on Lubuntu 18.04:

1. install xrdp server:

   sudo apt install xrdp
   sudo systemctl enable xrdp

2. In the /etc/xrdp/startwm.sh, you will need to comment (#) the last two lines and add at the bottom of the file, the following line, and SAVE:

   lxsession -s Lubuntu -e LXDE

   

3. Finally restart xprdp:

   sudo /etc/init.d/xrdp restart
