$ rm -f ~/.gnome2/keyrings/login.keyring
# nano /etc/pam.d/gdm3
ed inserire solo la riga rossa:
#%PAM-1.0
auth requisite pam_nologin.so
auth required pam_succeed_if.so user != root quiet_success
@include common-auth
auth optional pam_gnome_keyring.so
@include common-account
session required pam_limits.so
session required pam_env.so readenv=1
session required pam_env.so readenv=1 envfile=/etc/default/locale
@include common-session
session optional pam_gnome_keyring.so auto_start
@include common-pamkeyring
@include common-password
nel caso si volesse tornare ad avere la password, ricordarsi prima di eliminare "@include common-pamkeyring"
