[Pkg-xfce-devel] Bug#888027: xfce4-power-manager: possibly a lot of stuff broken because of libpam-runtime missing libpam-runtime option "2. Register user sessions in the systemd control group hierarchy"

[Cristian Ionescu-Idbohrn]

Package: xfce4-power-manager
Version: 1.4.4-4
Severity: important

Not setting "2. Register user sessions in the systemd control group
hierarchy" in libpam-runtime, when running under systemd init will
break most stuff under power-manager settings.

Unfortunatelly:

	# dpkg-reconfigure -p low libpam-runtime

does, no longer, reveal the current settings anymore :(  But:

	# debconf-show libpam-runtime

will (a novice can't be expected to know that).

Command:

	# dpkg-reconfigure -p low libpam-runtime

sorts that, without the need to hack all sorts or conf-files all over 
the place (at least not for me).

If you trust systemd for your init, then you should, at least, 
consider setting both:

  1. Unix authentication
  2. Register user sessions in the systemd control group hierarchy

when (re)configuring libpam-runtime.

That sort of documentation should (IMO) be presented up front, in some
form, in some obvious way, to avoid confusion, as xfce4-power-manager
installs files under /usr/share/polkit-1/actions directory.
