How can I make my PC hibernate when idle? 14.04

Question

I see that this was asked some time ago for 11.04.

The answer there didn't help since the answer used gconf-editor to find a key called /apps/gnome-power-manager/actions/, which doesn't exist when I look in my install of 14.04.

This setting must be stored somewhere else?

Installed gconf-editor (the setting was not in there) and updated the question. Thanks TuKsn. — i did not pay the royalties, Aug 08 '14 at 13:03
It may be somewhere in GConf. I didn't think ubuntu even had hibernate any more... — Tim, Aug 08 '14 at 13:19
Perhaps you should first enable hibernate http://askubuntu.com/a/94963/265974 — TuKsn, Aug 09 '14 at 15:33

Ubuntu Unity now uses dconf instead of gconf. Read this answer on how to modify settings.

The keys you are looking for are stored in org.gnome.settings-daemon.plugins.power.

For example

gsettings set org.gnome.settings-daemon.plugins.power sleep-inactive-ac-type 'hibernate'

will change the idle action on AC power to hibernate.

You can still set the timeout via system settings ("System Settings"->"Power"->"Suspend when inactive for..."), this will not reset the type to 'suspend'.
