No suspend after XFCE Power Manager added

[Lars Noodén]

I installed Lubuntu-core on a small machine and suspend (sleep?) worked
fine.  It suspended when I closed the lid and when I pressed the sleep
button.  I added xfce-power-manager to the machine to be able to see in
the panel how much power remains in the battery and since then the
machine does not suspend either when I close the lid or when I press the
sleep button.  Also, even though the power manager settings say "ask"
when the power button is pressed, nothing happens any more when I press
it.

I don't need the power manager but I do need suspend (sleep?) / resume
and would very, very much like to have an easy way to track power
remaining in the battery.

This is on Lubuntu 14.04 LTS on a Celeron M processor.  Can anyone
suggest a way around this?

Regards,
Lars
