Thank you Martin for your patch. I verified it as comment #8 suggested, after upgrading systemd to 204-5ubuntu20.1 on trusty: a) with swap partition enabled, there is the "hibernate" option in the menu, click it can enter S4 successfully. b) with swap partition disabled, there is no "hibernate" option in the menu. c) with swap file enabled, there is the "hibernate" option in the menu, click it can enter S4 successfully.
So, everything just works as expect, I'll change the tag from verification-needed to verification-done. ** Tags removed: verification-needed ** Tags added: verification-done -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1313522 Title: There is hibernate option even without an active swap partition To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/1313522/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
