déconnexion gdm

2006-03-15 Par sujet Roland JARRY

Bonjour,
Certains clients NIS avec leur home directory sous NFS ont quelques
problèmes à la déconnexion de gdm lors de la fermeture de session.
Ils ont le message suivant après avoir sélectionné clore la session :
Impossible de communiquer avec GDM. (le gestionnaire de connexion de
Gnome)
Peut-etre que vous avez une ancienne version de GDM en cours de
fonctionnement.
Il n'est plus possible de se déconnecter sans faire un CTRL+ALT
+BACKSPACE ou de killer deux processus correspondant à gdmflexiserver et
gnome-session.
Ce message n'apparait pas à chaque fois et je suis certain que ces
utilisateurs ne sont pas connectés deux fois.
J'ai ce problème depuis la migration en sarge et aucun problème avec un
home directory local et client NIS.

Si quelqu'un à une idée... Peut-être un paramétrage qui m'a échappé
dans /etc/gdm/gdm.conf, dont voici ma configuration :

# GDM Configuration file. You can use gdmsetup program to graphically
# edit this, or you can optionally just edit this file by hand. Note
that
# gdmsetup does not tweak every option here, just the ones most users
# would care about. Rest is for special setups and distro specific
# tweaks. If you edit this file, you should run:
# /etc/init.d/gdm reload or /etc/init.d/gdm restart

# For full reference documentation see the gnome help browser under
# GNOME|System category. You can also find the docs in HTML form
# on http://www.jirka.org/gdm.html
#
# NOTE: Some of these are commented out but still show their default
values.
# If you wish to change them you must remove the '#' from the beginning
of
# the line. The commented out lines are lines where the default might
# change in the future, so set them one way or another if you feel
# strongly about it.
