Since the time I've moved to Linux Mint 15 Cinnamon, I'v never had the hibernate option.
I tried following instructions at http://www.linuxandlife.com/2012/06/how-to-enable-hibernation-in-linux-mint.html but to no avail,even trying to change the Re-enable to enable but with no luck.
I can see there already is a com.ubuntu.enable-hibernate.pkls in /etc/polkit-1/localauthority/50-local.d/ (it's a pkl*s* not a pkl*a*)
For the record, when I do sudo pm-hibernate it just makes the system hang.
This is what dconf editor currently shows: http://i43.tinypic.com/ndtzec.png
Would really appreciate some help on this, pls.
