I have Kubuntu 16.04 64-bit installed on my HP Pavilion 17-f000 Notebook. I've tried the steps from the ubuntu 16.04 wiki, but the sudo pm-hibernate terminal command did nothing and creating the /etc/polkit-1/localauthority/50-local.d/com.ubuntu.enable-hibernate.pkla file with these contents also had had no effect:

[Re-enable hibernate by default in upower] Identity=unix-user:* Action=org.freedesktop.upower.hibernate ResultActive=yes
[Re-enable hibernate by default in logind] Identity=unix-user:* Action=org.freedesktop.login1.hibernate;org.freedesktop.login1.hibernate-multiple-sessions ResultActive=yes

I have 5.8GiB ram, 7.5GiB swap partition, and suspending to ram works fine.

    How large is the swap partition. Suspend to disk, aka hibernation, doesn't work if swap size is less then RAM. – mikewhatever Apr 23 '16 at 19:16

    My swap partition is 7.5 GiB and my ram is 5.8 GiB. – Enkouyami Apr 23 '16 at 20:08
  • Adding resume=/dev/myswapdevice to my /etc/default/grub and running sudo update-grub – Enkouyami Apr 25 '16 at 8:16
  • does not help. I didn't notice I didn't complete my previous comment. – Enkouyami Apr 25 '16 at 22:19
  • As regards the piece of docs you linked to (which is part of the official documentation), it's out of date and will be updated in a few weeks. Please see launchpad.net/bugs/1575466 – Gunnar Hjalmarsson Jun 12 '16 at 19:51

This is probably due to changes & regressions introduced in the 4.4.0 kernel such as this with Ubuntu 16.04, but I do have a workaround for 4.4.0:

I first added my swap partition to grub, rebooted, and there was no change. Next I installed the Ubuntu kernel packages with TuxOnIce stable and the option to hibernate appeared, but that failed. I later I installed the package hibernate which uses uswsusp for suspending to disk & ram and that worked. Below are the exact steps to achieve this:

  1. Double check if your swap partition/file(s) are setup correctly in /etc/default/grub; you can do so by checking the location with either cat /proc/swaps or swapon -s.

    Better yet, find out the UUID or label of the swap partition/files(s) and use that:

    tail -n -9 /proc/swaps | cut -d ' ' -f 1 | xargs sudo blkid
  2. Edit /etc/default/grub by finding the line with GRUB_CMDLINE_LINUX_DEFAULT=, add your swap device(s), and save. To enter the UUID, prefix it with UUID= or /dev/by-uuid/.

  3. Save changes to GRUB:

    sudo update-grub
  4. Add the TuxOnIce stable repository:

    sudo add-apt-repository ppa:tuxonice/ppa
  5. Install TuxOnIce kernel & uswsup:

    sudo apt update
    sudo apt install uswsusp linux-generic-tuxonice tuxonice-userui
  6. Restart your computer (sudo reboot;)

    Hey, I am able to hibernate my system using ' sudo pm-hibernate ', but there is no option to hibernate(on click upon top-right settings icon). – Nikhil Verma Jun 27 '16 at 18:05

    @NikhilVerma try this answer: askubuntu.com/a/462480/51672 – Enkouyami Jul 13 '16 at 0:13

    So by "add your swap device" you mean add "resume=/dev/yourswap" ? – misiu_mp Jan 2 '17 at 6:35

    What exactly is meant by "add your swap device(s), and save. "? – Alex Jan 11 '17 at 19:34

    @Alex According to this (askubuntu.com/a/196365/187411) it means to append the string resume=UUID=[your UUID] to the string that is already there. For example GRUB_CMDLINE_LINUX_DEFAULT="quiet splash resume=UUID=549ae7468" – ossbuntu Oct 27 '17 at 16:21

I had the exact same problem in Ubuntu 16.04, and nothing seemed to help.

I finally figured out that I just had to disable Secure Boot in the BIOS menu. I had already done the steps suggested in the accepted answer, so I can't say whether they were necessary in my case.
