I have Xubuntu 15.04 installed and having some issues with Suspend. It Suspends fine when done from the command line or the shutdown menu or even by closing the lid. I have set the inactivity timer to 15 minutes using xfce power manager for suspend. However, it never suspends because of inactivity. When I log back in after the failure to suspend, I see this message on the top right: GDBus.Error:org.freedesktop.DBus.Error.AccessDenied: Permission denied
Anyone has any ideas of things to try. Is there any logs that can tell me what could be wrong.
