enable hibernate on Ubuntu 15.04

Question

how to enable hibernate on ubuntu 15.04 ?

NOTE: I tried sudo pm-hibernate but when it resumed my computer all the open applications were closed

My RAM size is 4GB, swap size is 6GB

output of sudo blkid; cat /etc/initramfs-tools/conf.d/resume

Do you have a swap partition? What is its size? What is your RAM size? — Pilot6, Jul 09 '15 at 17:08
If your swap size is greater that your RAM size, give output of sudo blkid; cat /etc/initramfs-tools/conf.d/resume — Pilot6, Jul 09 '15 at 17:12

Your problem is in not matching UUID. You probably re-created your swap partition after install. You can fix it by running

sudo tee /etc/initramfs-tools/conf.d/resume <<< "RESUME=UUID=de8544b3-7bca-4ff1-9a1c-755bcc6da7b4"
sudo update-initramfs -u -k all

and reboot.

To enable hibernation in shutdown menu you can use this answer.

Aren't Ubuntu supposed to use systemd now? Or is this part of the stuff they haven't ported yet? – AlMehdi Jul 09 '15 at 18:05
I did not try it yet. Maybe systemd command should be used. – Pilot6 Jul 09 '15 at 18:06
