Title:
  [xubuntu] Failing to sleep after inactivity - power manager error?

Status in powermgmt-base package in Ubuntu:
  Expired
Status in xfce4-power-manager package in Ubuntu:
  Invalid

Bug description:
  Newly installed XUbuntu 14.10 on 2 different machines but both
  experience the same problem.

  Problem:

  Failing to sleep after inactivity and a "xfce4 power manager error"

  When setting the machine in xfce4-power-manager to suspend after e.g.
  15 minutes the machine will fail to suspend.

  This is the message that meets me when I login after a failed suspend:

  Power Manager Error  
  GDBus.Error:org.freedesktop.DBus.Error.NoReply:
  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.

  I can suspend from the logout dialog box.

  The following command suspends the system just fine:
  $ dbus-send --system --print-reply --dest="org.freedesktop.UPower" /org/freedesktop/UPower org.freedesktop.UPower.Suspend

  $ xfce4-power-manager --dump
  ---------------------------------------------------
  Xfce power manager version 1.4.1
  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: False
  Has brightness panel: True
  Has power button: True
  Has hibernate button: True
  Has sleep button: True
  Has LID: False

  So I guess It's some kind of  auth or policykit issue.
