Problem with RDP on Ubuntu?

Question

linux

Hello!
There are a lot of instructions on the Internet for installing an RDP server on Ubuntu using the xfce graphical shell! And I need to install RDP with xRDP with Unity GUI (ubuntu-gnome-desktop). Having somehow found instructions in divine English, I began to try to install RDP and a graphical interface in WSL Ubuntu 18.04 LTS. But when connecting and entering the wrong password, it writes login failed to display 0, when you enter the correct login and password, the connection seems to occur, but instead of starting the graphical shell, a black rectangle appears :)! After searching the internet, I found the manual ., although the graphical interface is already installed there, only the terminal is used, so it will do, but there are additional packages and whether they need to be installed! How to solve the problem and install the Ubuntu graphical shell and get remote access via RDP to WSL?! Tell me, please, without ignoring!!!
