Laptop doesn't sleep when lid is closed (Xfce).

[Paul Isambert]

Hello,

I've set xfce4-power-manager to sleep when the lid is closed, no matter 
whether I'm on AC or battery. The problem is that it doesn't work.
Strangely, though, if I close the lid when on AC (resp. battery), reopen 
it and go on battery (resp. AC), the computer goes to sleep, and 
restarts immediately since the lid is open.

I've removed gnome-power-manager, but to no avail.

Any idea?

Best,
Paul
