Comment 7 for bug 939335

The "hibernate" option is now present, but greyed out, which I guess is because hibernation is disabled globally, which in turn I guess is because hibernation doesn't work in most cases (very sad that nothing has been done to fix that yet).

The "suspend" option is missing completely, though it is actually the action that is taken by default.
I wonder what happens if you change it and choose "turn off". You probably won't be able to ever set it to "suspend" again, which inconsistent with the fact that it is the one configured by default. On a fresh install, in the Power settings the current option is shown as an empty item, and it does not appear when you unfold the dropdown (see screenshot).

By the way, suspend does not work at all with low batter, see #1239402.
Perhaps that is the reason why it has been removed as a choice? But if so, then it shouldn't be the default one.

I can't understand how such huge issues don't get attention, when they are the most critical ones which are making Ubuntu a terribly unstable system which cannot be used safely.
