Enable Hibernate in Ubuntu 18.04 LTS [duplicate]
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.
Solution 1:
If you are OK with suspending instead of hibernating, you can try this:
-
Before you click "Power Button" - press "Alt"
OR
-
Click "Power Button" and hold it.
Solution 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
Solution 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.
