During the shutdown process, if the console=graphics option was used to boot the system, and the shutdown is triggered by the Xorg server, a progress status indicator is displayed. To prevent the progress status indicator from displaying, set the new splash-shutdown property of the svc:/system/boot-config SMF service to false, as follows:
# svccfg -s svc:/system/boot-config:default setprop config/splash_shutdown = false # svcadm refresh svc:/system/boot-config:default
