Add hibernate option on your ubuntu system

The hibernation function of operating systems is losing popularity due to the rise of solid state hard drives (SSD) that greatly accelerate the loading speed of the system. However, there are still many users who only have traditional mechanical hard drives and who can greatly benefit from Ubuntu's hibernation option.

How to activate hibernation in Ubuntu

The hibernation function saves the state of our computer on the hard disk so that we can start it much faster than if we shut it down in the traditional way. This function is disabled in Ubuntu by default but it is very easy to activate it in order to use it. To activate the hibernation function in our Ubuntu we only need to create a small document file with the following name: com.ubuntu.enable-hibernate.pkla.

Once created, open it and copy the following lines inside:

Identity = unix-user: * Action = org.freedesktop.upower.hibernate ResultActive = yes Identity = unix-user: * Action = org.freedesktop.login1.hibernate; org.freedesktop.login1.hibernate-multiple-sessions ResultActive = yes

We just have to be careful to change the * symbol for our username on lines 2 and 6.

Once the content has been copied, we only have to save the document and close it. Next we open a terminal and write the following line:

one	gksudo nautilus

This will open a Nautilus window with administrator permissions. Once open we head to the path /etc/polkit-1/localauthority/50-local.d . Once we are in the path we will paste the text file that we have created before. Once this is done we will have the option to hibernate when we go to turn off our Ubuntu.

A very simple process, although we must bear in mind that the system needs a fairly large swap partition, as this is where it will store all the information from our session and that stored in RAM. We recommend that you put all your files safe the first few times before hibernating to make sure it works well.
