I agree and the change I made (mentioned earlier mail) doesn't effect
other displays.

That's good argument and users don't need to change/select language twice
to have both greeter and their own sessions to be the same langauge.

I have one point that seems likely to cause confusion a bit.

Let's say we have one option for language change to both greeter and
users'session. Remember that, at this point (before users start typing
their users' name/password), gdm2 doesn't have any clue of who's the user
and therefore, gdm2 doesn't know what was the last language ("Last")
of which user is. My question is .....
What does it mean when users select "Last" at this language selection
toward "greeter" ? What langauge is it for greeter to be restarted ?
