First, install xrdp
Ubuntu 16.04 just needs to install xrdp.
# apt-get install xrdp
Ubuntu 14.04 also needs to install vnc4server
# apt-get install xrdp vnc4server
At this point using the client connection, you should be able to connect successfully.
The command line screen appears in Ubuntu 16.04.
Ubuntu 14.04 screen is blank.
Second,Install a compatible desktop environment
Compatible desktop environments include gnome-classic, xfce, mate, etc.
Unity is not compatible.
Choose one of the following two.

# apt-get install xfce4
This is the core part of xubuntu's desktop.
2, exquisite and easy to customize mate
# apt-get install mate-core mate-desktop-environment mate-notification-daemon
Third, use the client connection
Win10 is available with "Remote Desktop Connection".
Linux recommends using Remmina.
