I Am trying to login to Ubuntu machine from windows using RDP. Installed `xrdp` and tight vnc but while connecting am getting following error 

```
xrdp_mm_process_login_response:login failed

```

Steps followed to install XRDP:

```
sudo apt-get update .
sudo apt-get install tightvncserver
sudo    apt-get install xrdp
sudo restart

```

After this tried logging with RDP and getting the error. could you give a step by step guide or other alternative methods, please?
