I can confirm the similar issue (Ubuntu 12.04 LTS with latest udates) - if I select "Suspend", then screen goes blank but doesn't turn off. And I have the same problem with hibernation.

I believe this is a duplicate of bug #962798 so marking it so. In that bug there is also an upstream bugzilla link that follows the progress on getting the issue fixed out-of-the-box.
