On the one hand this works reliably on Windows and OS X (for very different reasons and implementations) so I'd like to see it work here too, but at the moment my bias is to relegate it to experts to wade the mine field. And that means in DE's to hide all hibernation related GUI elements by default, and also by default to poweroff in low battery situations. And hopefully there's adequate messaging to apps when poweroff is called so states can be saved by those apps. -- Chris Murphy _______________________________________________ kernel mailing list kernel@xxxxxxxxxxxxxxxxxxxxxxx http://lists.fedoraproject.org/admin/lists/kernel@xxxxxxxxxxxxxxxxxxxxxxx
