[Bug 1605189] Re: Authentication is required for suspending the system

[chrisc1073]

I have the same problem using XFCE on Ubuntu 17.10.  But Markus's
solution does fix the problem.

My setup is as follows:

In XFCE Power Manager under the security tab set:
Automatically lock the session to "Never"

Uncheck "Lock the screen when the system is going for sleep".

Under the display tab I still blank the screen after 15 minutes.  Put to
sleep and Switch off times appear to be disabled (greyed out).

Under the system tab I still have system sleep mode going to "Suspend" after an hour.
Interestingly the screen still locks when it suspends.

So everything still works fine and as I want it to. I get a full screen
white on black message when I activate the machine again telling me the
screen is locked and to wait a few seconds for a dialog box to appear.
Haven't seen that before but fine nonetheless.

Title:
  Authentication is required for suspending the system

Status in systemd package in Ubuntu:
  Confirmed

Bug description:
  Automatic suspend from the xfce power manager does not work, as a
  window opens and asks for my password. Well, if it wants to suspend
  the system after a given timeout, I cannot enter my password as I'm
  not in front of my system then. Once I'm able to enter my password it
  is too late to run the suspend action.

  The window asking for my password prints:

  Password: <field-to-enter-the password>
