I have tried, but there was no successful result. when I logged with Root user, and execute: ---------------------------------------- [root@localhost ~]# gnome-power-manager --verbose --no-daemon (gnome-power-manager:19712): GnomeUI-WARNING **: While connecting to session manager: Authentication Rejected, reason : None of the authentication protocols specified are supported and host-based authentication failed.
