Bug#415064: The fact that desktop-base prevents KDM's usual configuration should be better documented

[Olivier Cappe <comcap@free.fr>]

I think the problem here is more the fact that it is presently unclear (in etch
I mean) that desktop-base indeed prevents KDM's customization the usual KDE way
("Control Center -> System Administration -> Login Manager"). Not only is it
impossible to make the users list visible but it is also impossible to change
the login appearance (other features such as passwordless users do work
however).

Something like "Users who intend to customize KDM (appearance and/or
functionalities) should not use the desktop-base package" should be clearly
visible somewhere (I spent quite some time finding that I needed to purge the
desktop-base for my settings to be taken into account).

Regards.
