Package: systemd Version: 232-1 Since systemd 232, lightdm's menu entries to shutdown/reboot/suspend/hibernate the system are grayed out.
Furthermore, GNOME polkit authentication agent fails to start (I use openbox, with the agent normally started from ~/.config/openbox/autostart). When manually run in a terminal, it immediately exits with the error message: "polkit-gnome-1-WARNING **: Unable to determine the session we are in: No session for pid ..." Downgrading systemd/libsystemd0/libpam-systemd to version 231-10 fixes the problem (I also tried 232-1 and 232-2, but they didn't work either). Sorry for the vague bug title (and the probably wrong binary package), but it's the best I can do since I'm not at all familiar with the way systemd/polkit/pam/lightdm/whatever interact with each other. Also, I just spotted this bug today despite the fact that it was introduced two weeks ago, because I rarely shutdown my sid box. Regards, -- Raphaël Halimi
