This is NOT an April Fools joke. Ubuntu has not deployed any April Fools jokes to its users since the Warty Warthog days (when a somewhat hairy parody of the welcome screen picture was deployed to beta testers).

actually it's

sudo shutdown -h NOW

The NOW has to be recited out loud screaming, using your best Arnold Schwarzenegger impression.

Hmm, i just always used:

Code:

sudo halt

I never understood why I need root privileges to do it in the terminal, but using the GUI I don't.

I do, GDM the display manager or KDM if you use KDE, will startup with root privileges, it will allow GNOME and KDE things without sudoing, GNOME uses root privileges, a normal terminal does not.

Thanks for the explanation.

There are dbus hooks that the GUI uses to request a shutdown; the authorization to do this can be set via PolicyKit; by default the foreground active user is always allowed to shutdown/restart; but you can configure that otherwise if you dont' want your users to shut down the system.

These same hooks can be accessed from the command line but it's not obvious. The GUI does not directly use the shutdown -h now command.
