Something I usually do after installing Ubuntu is reactivate the hibernation function. I find it quite useful to function for the more energy concious.
Typically, I'd complete the instructions in this tutorial for Ubuntu 12.04 and I'd be back in business. However, it does seem to work any more. Any suggestions?
