if no action is taken, the "Shutdown" feature is auto-executed abter 60 seconds.
Of these, only "Shutdown" and "Cancel" always have the intended effect, where "Shutdown" invokes a shutdown of the system and "Cancel" simply closes the dialog.
"Restart" causes a system restart in about 99% of the cases only, however I had seen occasions where only the session got terminated and the login screen is presented without an actual reboot taking place!
"Suspend" and "Hibernate" have NO effect, other than the dialog closes, in fact they behave the same as if "Cancel" has been pressed!
When "Suspend" or "Hibernate" are selected manually in the power menu from the Unity desktop, they both work. In fact all options in that menu work.
