hibernation offered even though hibernate is not available
Going to
Applications Menu -> Settings -> Power Manager -> System (button)
I can choose 'Hibernate' for what to do 'On critical battery power'.
But when the critical power is reached, it does not hibernate. Rather, a popup appears; it says there is not enough swap space for hibernation to be possible.
I guess this is consistent with the fact that, when I click the "Action Buttons", 'Hibernate' is grayed out (along with 'Hybrid Sleep').
My point is that, if hibernation is not possible, it should not be offered as a possible setting.
(Incidentally, I can adjust the 'Critical battery power level' to anything between 0 and 100%, either manually or by clicking on the -/+ buttons, but I find that if I input anything above 20% it is reset to 10% after closing and coming back.)
