我希望能够自动挂起然后休眠xfce4-power-manager，尽管我不确定这是否可行。
我相信这是一个权限错误，polkit1因为：
$ xfce4-power-manager --dump
---------------------------------------------------
Xfce power manager version 1.6.1
With policykit support
With network manager support
---------------------------------------------------
Can suspend: True
Can hibernate: False
Authorized to suspend: True
Authorized to hibernate: False
Authorized to shutdown: True
Has battery: True
Has brightness panel: True
Has power button: True
Has hibernate button: True
Has sleep button: True
Has LID: True
我的 polkit settings under/usr/share/polkit-1/actions/org.freedesktop.login1.policy are identical for suspend and hibernate, so it doesn't make much sense …
