In GNOME 3.8 the new behavior will use “pressure sensitivity” (a composite of speed and distance) and you will have to push down against the screen edge. That will mean two things:
First, it will be faster, the one second delay is gone
And second, it will mean you don’t get accidental triggers if you leave the pointer at the bottom of the screen.

But in my desktop, I still get the behaviour from 3.6: move the mouse to the bottom and the notification area appears after 1 second delay.
Is there any way to enable the pressure thing, or is it something still missing in Sabayon?
