I've been analyzing the list of packages that are having problems and comparing with my packages.
And what draws the most attention is the libglib2.0-0, which is the package that I have more updated and it's dependence on GDM3. Compared with a live version of UbuntuGnome 13.10 which uses GDM 3.8 and notice how dependency libglib2.0-0 (> = 2.37.3) and libpam-systemd. They are only suppositions, but may be a path. I use systemd, do not believe that is why my GDM is working, because Ubuntu still uses upstart.
