No. Help needed.

Luca, can you verify that in your jessie test setup?

Is there anything consolekit related installed?

* ensure that your user account is *not* in group video (I think the
first user created upon installation may be added to a few more groups
including video ...)
* ensure that Debian-gdm is in group video
* use nvidia-driver from backports (that should load with root:video 0660)

Expected: gdm starts, what about using glx as a user?
