Easily Get Hibernate Back in Ubuntu 12.04 [PPA Available]

Few days back, we reported that Hibernate option is disabled by default in Ubuntu 12.04 and enabling hibernate required changing some system files manually.

However, a nice PPA is now available which will enable hibernate on Ubuntu 12.04 without any need to manually change system files.

Just run the commands below and then re-login to get hibernate back:

sudo add-apt-repository ppa:vanhoof/policykit-d-p-hibernate-enabled

sudo apt-get update

sudo apt-get upgrade

To revert, first run the commands below:

sudo apt-get install ppa-purge

sudo ppa-purge ppa:vanhoof/policykit-d-p-hibernate-enabled

Now run:

sudo gedit /etc/polkit-1/localauthority/50-local.d/com.ubuntu.desktop.pkla

Remove following lines and reboot.
