Description of problem: F18 RC3-Alpha Xfce spin running live. On the lightdm login screen the power menu that should show shutdown/reboot/suspend is empty. Version-Release number of selected component (if applicable): How reproducible: always. Steps to Reproduce: 1. boot live-cd to lightdm screen. 2. 3. Actual results: 'power' menu empty. Expected results: 'power' menu functional. Additional info:
I see the same with lightdm-1.3.3-2 and lightdm-gtk-1.3.1-1 on Fedora 17. So it is not the Fedora releases that has changed but lightdm internals.
Sorry for my ignorance and spamming but reading this gnome-shell issue at https://bugs.freedesktop.org/show_bug.cgi?id=53905 I thought if it couldn't be some ConsoleKit induced conflict that disables the power options.
confirmed with both -gtk and -kde greeters, I suspect some consoleKit fail going on, investigating...
apparently all ConsoleKit-related calls are returning insufficient permissions, for example, return ck_call_function ("CanStop", FALSE, NULL); and even when I comment out the CanStop check, and allow the UI buttons to show, they don't work.
Reassigning to ConsoleKit, any clues why lightdm greeter calls to ConsoleKit dbus methods org.freedesktop.ConsoleKit.Manager.CanRestart org.freedesktop.ConsoleKit.Manager.CanStop are returning false?
In the meantime, looks like implementing the lightdm systemd shutdown/restart bits may be worth doing now (bug #867924)
Yeah, as I said, ConsoleKit should already be dead and gone, LightDM needs to stop beating a dead horse (or worse, trying to ride it ;-) ).
Thanks for this insightful comment, I am sure it will help us fixing the problem.
looks like it's a policykit thing, and Tim Lauridsen is the hero for figuring that out, see bug #872797
