Comment 50 for bug 1178373

In xfsm_shutdown_try_suspend the logic is:
SystemD ? use LoginD suspend
Upower < 0.99 ? use Upower suspend
Otherwise lock the screen and call pkexec xfsm-shutdown-helper --suspend

http://git.xfce.org/xfce/xfce4-session/tree/xfce4-session/xfsm-shutdown.c#n312

Same for hibernate. I've been testing with a system that has consolekit + upower git master (it calls itself 0.99.2). Or is this for systems without polkit installed (or polkit-gobject-1 which is used for the fallback instead of sudo)? Just trying to figure out where it's gone wrong so we can fix it.

Does pkaction --action-id org.xfce.session.xfsm-shutdown-helper -v return anything?
