lock screen

[Patrick Dupre]

Hello,

I am 2 machines with fedora 16.
On one the screenlocking works fine, on the other one, it does not 
work.

The screen is never lock after 10 min (Lock ON) as required.
In addition, when I click on "Lock Screen" nothing happens.
But, if I dial xlock, it turns the screen locked.
What did I miss ?
Is a service missing?

Thank
