I'm experiencing precisely the same issues, as well as a strange glitch
wherein whenever my screen is blanked (either automatically or manually
via xset dpmd commands) it cycles on and off and then dumps me back at
the unity-greete. Whenever this happens I'm not logged but it is rather
odd because typically (i.e. when I lock the screen) Ubuntu will lock the
screen with gnome-screensaver (I think) rather than lightdm/unity-
greeter. I wonder if these two issues have the same route cause, being
at least tangentially related (i.e. power management issues).
If it is down to some package(s) monopolising or interfering with
vaguely power management related functions (e.g. screen blanking,
shutting down, restarting, etc…) the only package installed on my
machine that vaguely fits the bill is Synapse (it has inbuilt shutdown
and logoff commands and unlike indicator-session's equivalent entries
they work for the time being). I also have panethon/elementaryOS daily
packages (from their daily PPA) installed, but I can't see applications
like wingpanel, plank, slingshot-launcher, gala (which I don't even use)
and cerbere causing such mayhem (why would they even have need to touch
these functions?).
Anyway, I've tried killing synapse to see if doing so will 'release'
these power management functions and it didn't work. Perhaps I need to
reboot with synapse taken out of autostart to be sure. Also, I don't
even HAVE a restart option in my indicator-session menu. It appears
whenever I enable gsetting com.canonical.indicator.session. supress-
logout-restart-shutdown using dconf-editor but is not present otherwise.
