[Pkg-xfce-devel] Bug#729081: Suspend not working when closing lid

[Omen Nemo]

After a massive upgrade from gnome 2.xx to a nearly completely
up-to-date unstable mate+lightdm, closing the lid fails to suspend as
set in mate-power-preferences.
The acpi event is correctly detected:

# acpi_listen
button/lid LID close
button/lid LID open

but I see the following:

Apr 19 02:42:15 machine dbus[2295]: [system] Activating service
name='org.freedesktop.systemd1' (using servicehelper)
Apr 19 02:42:15 machine dbus[2295]: [system] Activated service

return code 1

Looking at the thread for the various related bugs, maybe the
following information will help:
