My Ubuntu 12.04 is missing Hibernate option so after searching a little on Google I came to know that this can solve my problem

sudo nano /etc/polkit-1/localauthority/50-local.d/com.ubuntu.enable-hibernate.pkla

Fill it with this

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

Here is the link : How to enable hibernation?

After doing this I restarted my system. when the system booted it hanged ike anything No mouse movement no terminal no nothing. I waited for more than 1 hour Hibernate option appeared but i was not able to use my system anymore. any ideas ?

    Now I have a hibernate option in the power tab but it just turns off my system like Shutdown. and when I restart my system it is a fresh new session. No resume of my work. – Hussain Nagri Jul 27 '12 at 8:30
  • @HussainNagri in this post, there is an instruction to test whether hibernation works on your machine before enabling it. That test is sudo pm-hibernate. Did you run that test to see if hibernate works on your system or not? – Thomas Ward Aug 2 '12 at 13:14

One possible cause of being unable to hibernate is if you encrypted your home directory (and with it your swap partition).
