[How-to] Enable HIBERNATE in Ubuntu

I enabled Hibernate in my Ubuntu 14.04 by following these:

To enable the Hibernate menu
as instructed by http://ubuntuhandbook.org/index.php/2014/04/enable-hibernate-ubuntu-14-04/

~$ sudo vi /var/lib/polkit-1/localauthority/50-local.d/com.ubuntu.enable-hibernate.pkla
   [Re-enable hibernate by default in upower]
   Identity=unix-user:*
   Action=org.freedesktop.upower.hibernate
   ResultActive=yes

   [Re-enable hibernate by default in logind]
   Identity=unix-user:*
   Action=org.freedesktop.login1.hibernate
   ResultActive=yes

   [Re-enable hibernate for multiple users by default in logind]
   Identity=unix-user:*
   Action=org.freedesktop.login1.hibernate-multiple-sessions
   ResultActive=yes


Setup SWAP as space to hibernate
as instructed by https://help.ubuntu.com/community/SwapFaq
 
~$ sudo blkid
   Copy the UUID of swap

~$ sudo vi /etc/default/grub
   Look for the line GRUB_CMDLINE_LINUX=""
   Replace with GRUB_CMDLINE_LINUX="resume=UUID=yourUUID"
 
~$ sudo update-grub

~$ sudo vi /etc/initramfs-tools/conf.d/resume
   Ensure that it contains RESUME=UUID=yourUUID

[How-to] Mount /home to another disk partition

I need to free up some space in my linux(Ubuntu) main partition. I decided to move my /home folder to another partition. So I did the following, as instructed here, https://help.ubuntu.com/community/Partitioning/Home/Moving:

~$ sudo blkid

~$ sudo cp /etc/fstab /etc/fstab.$(date +%Y-%m-%d)

~$ cmp /etc/fstab /etc/fstab.$(date +%Y-%m-%d)

~$ sudo gedit /etc/fstab

    and appended

    UUID=????????  /media/home  ext4  defaults  0  2 

~$ sudo mkdir /media/home

~$ sudo mount -a

~$ sudo rsync -aXS --exclude='/*/.gvfs' /home/. /media/home/.

~$ sudo diff -r /home /media/home

~$ sudo gedit /etc/fstab

     and edited /media/home to /home

~$ cd / && sudo mv /home /old_home && sudo mkdir /home

~$ reboot

~$ sudo rm -r /old_home

~$ sudo rmdir /media/home
