c'est déplacé comme commentaire dans un bug tracker c'est tout (end of
the discussion on that topic)

> Yes, I think you're often too prompt to reassign bug reports when they
don't mention gnome/unity/something-managed-by-the-desktop-team, without
thinking about the real issues or even reading the bug... And we usually
end up doing some funny ping pong sessions because we're both stubborn
and don't listen to each other?

Right, side effect of having to deal with tons of bugs, we can't spend
hours on every ticket and errors happen, no need to come back with
personal attacks and "bug stat" speculations when that happens. I'm
happy to admit I do reassing bugs quickly and do errors sometimes (or
often if you prefer), nobody is perfect

greeter instead of doing that,

Selecting as a random greeter is a no from the discussion we had with
Robert in the past, he thinks that could be a security issue and not
something reliable, it's better to break the config and have xfailsafe
kick in to let you fix,reset the configuration

Why is the greeter set to ""? That seems a bug in lightdm-set-defaults
--remove, i.e it should remove the line (and let lightdm goes back to
use its build time default)?

update-alternatives). Voilà.

I will let others to decide on that, I hate alternatives they are
overcomplex and tend to create issues, but I will not stop the lightdm
maintainer to use them if he wants.


One other questions on that issue would also to know why the xfailsafe mode 
doesn't kick in, that's what is supposed to happen when no greeter can be loaded
