gdm, startx ... (URGENT)

[Alberto Maurizi]

        After upgrading Xfree to 3.3.6, some problems arose:
        - gdm no longer works (/etc/init.d/gdm starts does nothing)
        - startx as user says
                        "X: you are not authorised to run the X server"

        Any idea?

        Thanx,
        Alberto
