@Charie, as sayd by Chris Coulson in comment 12 I modified the entry Exec, in /etc/xdg/autostart/nm-applet.desktop, from
Exec=nm-applet --sm-disable to Exec=sh -c 'GTK_DEBUG=plugsocket && nm-applet --sm-disable' I haven't understood if I should add another entry too (that is "Exec=sh -c 'GTK_DEBUG=plugsocket && gnome-panel'"). and after system reboot nothing happened and my .xsession-errors was: " /etc/gdm/Xsession: Beginning session setup...
