Linux Hibernation in short

In order to hibernate in Linux, you need a user space script and an backend. Two User space scirpts widely used are:

  • pm-utils : used in OpenSuse, Ubuntu, etc
  • hibernation-scirpt : used by gentoo, etc

The linux kernel comes with hibernate backend named swsusp but you can also try other tool, so your options are:

  • uswsusp : need to be installed
  • tuxonice : you got to patch the kernel
  • swsusp : comes without extra effords

My choise is pm-utils + uswsusp for I’m too lazy to patch and compile a kernel, and I’ve been using pm-utils for a long time.

And one more thing to mention, even hibernation-script comes with tuxonice, it can use uswsusp as backend.
