Somehow this was fixed for me by the following (almost random) sequence of steps:
1. remove resume/resume_offset kernel parameters from /etc/default/grub 2. update-grub, reboot: hibernate options appear in ubuntu shutdown menu 3. hibernate: works, no more "invalid argument" error. 4. resume(power on): not works - just regular power on. Tried several times. 5. return resume/resume_offset kernel parameters back to /etc/default/grub. 6. initramfs -c -k all : maybe this fixed it? (should not be necessary to do) 7. update-grub 8. hibernate 9. resume: works (!) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2057687 Title: systemctl hibernate error: "Call to Hibernate failed: Invalid argument" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/2057687/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
