Enable Hibernation on Ubuntu 14.04 LTS Trusty Thar

By default "Hiberanation" option is disabled on your Ubuntu Os.Hibernation option is very useful when we want close the laptop (or) system but want our applications in the open state so that we can continue the work where we left the other day when we switch on the laptop (or) system.

Test Hibernation :-

First , We need to check whether Hibernation works on our system or not.Open the terminal using Ctrl+Alt+T

Type the below Command in terminal to test Hibernation:-
sudo pm-hibernate

After entering the command it prompts us to enter the password. After typing the password now the laptop Hibernates. Switch-on the Laptop/system it should return back all the applications folders and files as they were before .
So, if you want to hibernate your system everytime run the sudo pm-hibernate command in terminal.If you dont like to run the command you can add hibernate option in the menu tray.

Enable "Hibernate" option in the Power Menu tray

1) You need to create a file.For that run the following command in the terminal

2) Now paste the below code into newly created file:
[Re-enable hibernate by default in upower]
Identity=unix-user:*
ResultActive=yes

[Re-enable hibernate by default in logind]
Identity=unix-user:*
