How to enable Hibernate in 12.04?

I just installed the new 12.04 beta on my Lenovo Ideapad U450. According to this thread Whither hybrid suspend? hibernate and suspend are supported, but in the power settings the option to hibernate is greyed out e.g. for what to do when closing the lid. How can I enable it?

My goal is, that if suspend to both is not supported a behaviour something like, suspend to ram and when battery is low, suspend to disk. Is this possible?

  • Your other question was closed because this site does not support the current alpha and beta versions. If you have questions about the currently supported versions like 10.04, 10.10, 11.04 or 11.10, feel free to ask them. If your question is about 12.04, which is not yet released to the general public, it will be most probably closed.

  • I bet your RAM > swap. Your swap needs to be at least the size of your RAM, otherwise you can't hibernate, only suspend (to RAM). Mar 3, 2012 at 12:01
  • Ok, I bet I would have the exact same problem in any other version too. Open Source is in great parts alpha or beta, so I think questions about things on not supported versions are valid. Would this forum be so rude if I'd have 11.10. installed?

  • @CS: I have swap in exactly the same size as my ram (4GB) and it is enabled. Should I make it bigger?
