Nu pot modifica nimic în Autologin - gdmsetup

Am instalat linuxmint-debian-201012-gnome-dvd-amd64 dar nu pot modifica nimic nici măcar cu "sudo gdmsetup" în terminal.
Asta este ce îmi dă în terminal

Cod:

** (gdmsetup:3722): DEBUG: init delay=30
** (gdmsetup:3722): DEBUG: GdmUserManager: scheduling a passwd file update
** (gdmsetup:3722): DEBUG: GdmUserManager: reloading passwd file worker
** (gdmsetup:3722): DEBUG: GdmUserManager: include_all is FALSE
** (gdmsetup:3722): DEBUG: GdmUserManager: done reloading passwd file
** (gdmsetup:3722): DEBUG: Failed to identify the current session: Unable to lookup session information for process '3722'


mulțumesc
