The GDM log suggests the currently LightDM behaviour is the same. In that case we should revert the u-c-c change (and lose the ability to hide non graphical logins). We could filter out non-graphical logins by checking if the tty is less than 7 (yes, it's a total hack) or look at making AccountsService change the value it provides for X cases (probably the better option).
Thanks Martin, Jeremy.
