I have newly installed Ubuntu 13.1 on my Sony Viao laptop and would very much like to have a sleep/hibernate functionality on my laptop (when I close the lid of my laptop). The following link told me how to enable hibernation, except that it seems like my laptop doesn't like hibernation.
When I try to put my laptop to hibernate and bring it back to life, it simply hangs and does nothing.
Would someone please be able to help me out with this? Step--by-step instructions would be greatly appreciated as I am very new to the world of Linux.
