I just installed a test machine with Ubuntu LTS 14.04 and I went to configure the XDMCP access and found that the file /etc/lightdm/lightdm.conf is not there anymore.

In Google I found that now it is in /usr/share/lightdm/lightdm.conf.d/50-ubuntu.conf and there I modified the settings to enable XDMCP and some others:

[SeatDefaults]
user-session=ubuntu
greeter-show-manual-login=true
[XDMCPServer]
enabled=true
[SeatDefaults]
xserver-allow-tcp=true

But when I try to log in using Xming from a windows machine, I can enter the username and password but afterwards no desktop appears, only the background from the login screen.

I created this file /etc/lightm/lightdm.conf:

[SeatDefaults]
xserver-allow-tcp=true
xserver-share=true
xdmcp-port=177
greeter-show-remote-login=true
[XDMCPServer]
enabled=true
port=177

Then I installed gnome-session-flashback because Unity doesn't work in the XDMCP client.
