Настройка автовхода в ligthdm

[Сергей Москвичёв <sernikmos@gmail.com>]

  Доброго времени суток!

Что-то не получается у меня сделать несекьюрный вход в систему.
Пробовал по этой подсказке http://siripong-computer-tips.blogspot.com/2011/09/enable-lightdm-autologin-debian-wheezy.html

Правлю в lightdm.conf

[SeatDefaults]
autologin-user=serega
autologin-user-timeout=0
pam-service=lightdm

в /etc/pam.d/lightdm ничего не правлю, просто привожу что он из себя представляет.

#%PAM-1.0
auth    requisite       pam_nologin.so
auth    required        pam_env.so readenv=1
auth    required        pam_env.so readenv=1 envfile=/etc/default/locale
#auth    sufficient      pam_thinkfinger.so
@include common-auth
auth    optional        pam_gnome_keyring.so
@include common-account
session required        pam_limits.so
@include common-session
session optional        pam_gnome_keyring.so auto_start
@include common-password

Перезагружаюсь, но автовход не работает. В логе
