How to re-enable hibernate option?

Question

I had enabled "hibernate" option in my Ubuntu 12.10 few months back by adding the following lines to /etc/polkit-1/localauthority/50-local.d/com.ubuntu.enable-hibernate.pkla:

[Re-enable hibernate by default]
Identity=unix-user:*
Action=org.freedesktop.upower.hibernate
ResultActive=yes

However, I don't know how, rather don't remember what led to it being disabled both in "power options" and in the "gear icon" on the menu bar.

The file is still intact.

One of the things I suspect is removing old kernels using Ubuntu tweak, but have no valid reason to allege this :P

I had to create that policy file in /var/lib instead of /etc (Ubuntu 14.04). After killall unity-panel-service it immediately appeared under the gear menu. — ᴠɪɴᴄᴇɴᴛ, Jul 22 '14 at 10:51

Ghosh... how did I take so long in discovering that I didn't have an entry for the swap partition in my /etc/fstab file?

The problem was, I had deleted my swap partition and then re-created it some days later, but did not realize that /etc/fstab had the old entry and the newer one was never added to it.

Adding the entry and rebooting my laptop now gives me the option to hibernate.

Try running sudo update-grub, occasionally this is necessary if you change grub settings or configurations. From the highest searched answer to this question: (How to enable hibernation?) "Some users will then need to run sudo update-grub to get the hibernate option to be available in the power menu.."

Thanks @handuel, but there is no change. – jobin Mar 06 '13 at 17:07
@Jobin Well, there would be no change. grub is the bootloader for Ubuntu (To Dual-Boot), so no change would happen. – horIzoN Mar 06 '13 at 17:13
@nerof61 I quote: "Some users will then need to run sudo update-grub to get the hibernate option to be available in the power menu.." – w4etwetewtwet Mar 06 '13 at 20:32
