~amd64 with gnome-overlay: gnome-extra/gnome-power-manager-2.27.92-r1 USE="X hal -debug -doc -policykit -test" When trying to set system to suspend (from g-p-m's menu on panel notification area), I get following warning: (gnome-power-manager:29335): devkit-power-gobject-WARNING **: Couldn't suspend: not authorized
I followed the latest g-p-m ebuild of the gnome-overlay for the last year. I see this bug since gnome 2.26, so I suspect devicekit-power or polkit to be the source of this error (shame on me for not opening a bug). I'm running x86, latest unstable with gnome-overlay.
