Enable Hibernate in Ubuntu 18.04 LTS

Question

How can I set Hibernation in Ubuntu 18.04 LTS (laptop)?

When I open the Power option > When the Power Button is pressed, I just see the following options:

• Suspend
• Power OFF
• Nothing

But does not show Hibernate.

Answer 1

If you are OK with suspending instead of hibernating, you can try this:

1. Before you click "Power Button" - press "Alt"

   OR

2. Click "Power Button" and hold it.

Answer 2

sudo systemctl hibernate

This did not work for me. I try pm-hibernate which did not work for me either until I added missing package uswsusp

sudo apt install uswsusp  

Answer 3

Use this, it is more recent. It worked for me with a new 18.04 install on my laptop. http://ubuntuhandbook.org/index.php/2018/05/add-hibernate-option-ubuntu-18-04/

Also, check that you have a swap file before you start. You should have one by default. Run

swapon --show

to check.
