Following this answer I was able to restore hibernation on my Ubuntu Vivid Vervet 15.04. Unfortunately after hiberate/restore all running programs are gone, as if it was a regular power-off.

Any hints?

Edit:

sudo blkid

/dev/sda1: UUID="c5d5f237-f70c-43db-bbeb-482b8c15bf33" TYPE="ext4" PARTUUID="559a5acb-01"
/dev/sda5: UUID="60a90294-7412-47fc-99e3-f2c69a9b1db0" TYPE="swap" PARTUUID="559a5acb-05"
/dev/mapper/cryptswap1: UUID="6d0b5a7c-f404-47e9-a641-b04dcde3a5c2" TYPE="swap"

cat /etc/initramfs-tools/conf.d/resume

RESUME=UUID=645b50f6-d568-4247-9f7b-a6bd07b21686

You hibernation does not work because you have a wrong UUID in your /etc/initramfs-tools/conf.d/resume file.

Run in terminal

echo "RESUME=UUID=60a90294-7412-47fc-99e3-f2c69a9b1db0" | sudo tee /etc/initramfs-tools/conf.d/resume
sudo update-initramfs -u -k all

  • But I am concerned about "cryptswap". Is your swap partition /dev/sda5 or you have an encrypted swap? – Pilot6 Jul 03 '15 at 16:57
  • this does not work for me - the same problems occur. do you have any other ideas? – alex Jul 04 '15 at 04:59
  • The idea is same. System must know from what partition to resume. If swap is encrypted, that may be an issue. If you do not need an ancrypted swap, i would remove it and update /etc/fstab and other settings. – Pilot6 Jul 04 '15 at 08:18

At the Official Ubuntu Documentation, it is already warned that hibernation may not work as expected, and suggests that test run before activating, and always save the work you are doing.

This is why the feature is not enabled by default.
