I have a similar problem on Ubunto 14.04 LTS where I installed XFCE : Launching the Power manager does nothing then after a few seconds a dialog display:
"Unable to get configuration information from xfce power manager: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken." Launching "xfce4-power-manager-settings" has the same result. Launching "sudo xfce4-power-manager-settings" asks me "Xfce4 Power Manager is not running, do you want to launch it now?" -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1242452 Title: xfce4-power-manager is not running by default with Lubuntu 13.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lubuntu-default-settings/+bug/1242452/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
