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!

Thanks for the information, was looking for that one for at least one hour tonight ...
(i can't believe it's still a such obscur configuration with each ubuntu version for such a simple thing, and moreover it changes too often (DisallowTCP, no-listen-tcp and now xserver-allow-tcp=true))

Thanks a lot for sharing!
I couldn't find it anywhere.
By the way, where did you get that information?
