[Bug 1532017] [NEW] No option to suspend when power critically low; hibernate option greyed out

 

Public bug reported:

(no idea whether this is the right package)

In Power Settings, under "on battery" and "when power is critically
low", the only available option is "Power Off". The "Hibernate" option
is greyed out, and the option "Suspend" doesn't even exist, which is
completely stupid.

Maybe hibernation is greyed out for the same reason why it's not available in the shutdown menu, that is, because it's unreliable as hell.
Besides the fact that it's about time to fix it, given we have already reached W in the alphabet of versions, anyway, since most of the time it works, the option should be available with a warning that it may fail to resume, rather than completely unavailable.

Regarding the "Suspend" option, it's simply stupid that it's not
available. I know, suspend requires a minimum amount of power. But the
solution to that is pretty obvious: if the selected choice is to
suspend, then use a slightly higher threshold for triggering suspension.
And if while suspended the power goes below the lower critical threshold
for keeping suspension, then it should wake up and hibernate, or turn
off (there should be an additional option for this).

I remember a few versions ago the option to suspend on low power did
exist, and what happened was that the system started to suspend,
immediately wake up, suspend again, and so on forever until the power
was too low and it just hard-powered off. Now, I understand that was
pathetic, but the new behavior is no solution. Also this proves that
waking up when power reaches critical level while suspended is possible.
