If you want to re-enable the 'shutdown' and 'restart' buttons on the login screen do this: * Edit the /etc/X11/gdm/custom.conf file and add the following under the 'daemon' and 'greeter' headings: === /etc/X11/gdm/custom.conf === [daemon] RBACSystemCommandKeys= [greeter] SystemMenu=true === END === * Restart the GDM service (or reboot) # pfexec svcadm restart gdm Note: This will kick you back to the login screen so save all your work before restarting GDM. * You should now see shutdown/restart under the 'options' button -- This message posted from opensolaris.org
