Salut
Sur SID cela peut se configurer en modifiant le fichier : /etc/gdm3/greeter.gconf-defaults
Ou via le lien symbolique qui pointe sur le même fichier dans : /usr/share/gdm/greeter-config/20_debian
Le fichier ressemble à ceci :
[code]# Use a specific background
/desktop/gnome/background/picture_filename /usr/share/images/desktop-base/Grunge.png
/desktop/gnome/background/picture_options zoom
Theming options
/desktop/gnome/interface/gtk_theme OverglossedBlack
Greeter options
/apps/gdm/simple-greeter/logo_icon_name debian-swirl
Play system beeps - especially the one when the greeter is ready
#/desktop/gnome/sound/event_sounds true
Some other possible options
#/apps/gdm/simple-greeter/banner_message_enable true
#/apps/gdm/simple-greeter/banner_message_text Welcome
#/apps/gdm/simple-greeter/disable_restart_buttons false
#/apps/gdm/simple-greeter/disable_user_list false
The lower panel doesn’t work with the compositor
/apps/metacity/general/compositing_manager true
Prevent the power management icon from showing up
/apps/gnome-power-manager/ui/icon_policy never[/code]
