I've deployed a Kali Linux 2.0 instance in a hosted data center and so far have ssh access to it, which is a great starting point. However, I'd love to also be able to access the machine via remote desktop. It is my understanding that Kali 2.0 include Gnome as the desktop environment and the gdm3 desktop manager seems to be running on the machine (and presumably would show a login on any graphics card connected to the actual machine). I've tried unsuccessfully so far to do a remote desktop login to the machine. I've edited the /etc/gdm3/daemon.conf file to add the following sections:

[daemon]
RemoteGreeter=/usr/lib/gdm/gdmlogin

[xdmcp]
Enable=true

And then tried to connect via MobaXTerm from a Windows PC using an XDMCP session, but that doesn't seem to be sufficient.

What am I missing? Has anybody been successful in bringing up the graphical UI for a Kali Linux box hosted at a cloud provider location?
