[solved but need explication] restart, shutdown gray

[pd1986]

solved by emerging sudo package and mounting swap correctly



Hello, I have another problem about the power control on xfce4
I did what the site tell us to do (http://wiki.gentoo.org/wiki/Xfce)
which is Configuring policykit daemon. I also created another file for suspend/hibernate and udisk mounting authority.
However, suspend works, udisk mounting works, but hibernate, restart and shutdown are still gray. even I start x with root count, they are gray too.

Well, I have to let you that, restart and shutdown works in the last system that I've installed before, then I reinstalled system because the swap volume is too small to make hibernate work. so I reinstalled the system, the kernel is updated too, (the last version is 3.2.1-gentoo-r2) but this time restart, shutdown the hibernate are not possible.

Do you have any ideas?
Thanks

Desktop Env: xfce4
kernel: 3.2.12-gentoo

hibernate is solved, pb is due to the incorrect swap mounting.
but restart and shutdown are still impossible.

I have normal shutdown and restart buttons in the Xfce but I haven't any policykits. Also I want note that my my suspend is called with a desktop icon by me.

problem solved.

installed sudo package, and buttons become available but need password to launch. So I add nopasswd to my count in visudo, then it works.

However I don't understand, I am not authorized by configuring polkit and consoledkit. I examined the polkit configuration. Generally, the group wheel is authorized by default. why do I also need sudo?
