A funny problem

I upgrade my ubuntu to 12.04 LTS,recently,and I got a new X-window called Cinnamon.

It let my desktop look more "windows".

But it has some little change.

That is it will suspend when the lid closed.

It seems that its the trick in power setting .

but the setting has nothing changed .

Afterward,,,I found that What I mean is that  I need to enter my password to unlock the screen.


so,,,the real setting that I need to set is on "Brightness and Lock"


let the lock closed,,,,,this shit was gone
