I enabled hibernation following this steps: How to enable hibernation in 15.04?
I can now see "hibernate" option and also hibernate seems to turn my computer off. But when I turn back on, it is like a regular boot, with all windows closed. Please help.
sudo pm-is-supported gives following result :
$ sudo pm-is-supported pm-is-supported [--suspend | --hibernate | --suspend-hybrid ]
Hibernating from the command prompt using
sudo pm --hibernate does same thing. Screen goes off, comes back in 1-2 seconds, and computers turns off. Starting closes all my work and boot like a regular boot.
