Hibernate via lid close broken?

["W. Martin Borgert" <debacle debian org>]

Hi,

with gnome-tweak-tool I changed the "Laptop lid close actions"
to "hibernate". However, when I close the laptop, a suspend to
RAM takes place. I'm using GNOME3 from Debian experimental.

Is this a known bug? Is there a solution?

TIA!

(So far, the only solution to hibernate under GNOME3 seems to
be "sudo hibernate". GNOME3 makes me feel young again, back in
the FVWM times, when neither KDE nor GNOME even existed :~)
