Ubuntu 11.10 and Remote X applications : lightdm

And now for something completely obscure ...

I recently attempted to telnet from an Ubuntu 11.10 workstation to a Solaris 10 server and found that I could not run X applications that displayed back to my Ubuntu workstation's X server.
In previous versions of Ubuntu the fix for this is well documented but the current version of Ubuntu uses LightDM instead of GDM and a completely different configuration.
Long story short, the fix involves editing /etc/lightdm/lightdm.conf and adding the following line:
xserver-allow-tcp=true
Reboot or restart lightdm and you should be good to go!
