Enabling hibernation in Linux Mint 20.2

[gabbo]

Hi,
I'm trying to configure my new PC with Linux Mint 20.2.
I'd like to enable hibernation (as I had in my previous Linux Mint PC). I have tried to run sudo pm-hibernate as a test, but it restarted afterwards normally and without the few programs I had open, even though it did a bit of flickering before shutting down (as the old pc would do).
I currently have 16 Gb of RAM and a 17.8 Gb swap partition in order to allocate all the RAM.
How could I make it work?
Thanks!

I was just looking for the solution to this problem myself, and just discovered the solution.

First of all, you will want to resize the swap partition to double the size of your RAM (in this case, 32 GB or 34,359,738,368 bytes), so that hibernation can safely suspend to RAM.

Second, make sure Secure Boot is disabled in your BIOS settings.

Third, open the command line (terminal), and type in the following:

sudo -i

(Type in your password)

Code: Select all

echo -e "[Enable hibernate in upower]\nIdentity=unix-user:*\nAction=org.freedesktop.upower.hibernate\nResultActive=yes\n\n[Enable hibernate in logind]\nIdentity=unix-user:*\nAction=org.freedesktop.login1.hibernate\nResultActive=yes" >> /etc/polkit-1/localauthority/50-local.d/enable-hibernate.pkla

Next, close that terminal window, and open up a new terminal window. Type in the following:

inxi -u

Copy the 'uuid' value of your swap partition to somewhere - you're going to need that later on.

Next:

sudo -i

(Type in your password)

xed /etc/default/grub

This will open up the text editor for the 'grub' file.

Look for the line of text that says

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

Now, you're going to need to paste the 'uuid' value from earlier. Change that line of text within the 'grub' file to

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash resume=UUID=PASTE THE UUID VALUE HERE"

Save the 'grub' file, and close the text editor.

Finally, in a new terminal window, type in the following:

sudo update-grub

(Type in your password)

After that, restart your computer, and then make sure hibernate works properly thereafter.

This worked fantastically.
I had tried using a swapfile on the same partition which failed.
The separate swap partition worked straight away.

Thank you.

Just curious ... what does that long line starting with the echo?
It seems it is writing to a file, but that is not the /etc/systemd/logind.conf where I would expect this sort of configuration to take place?

Hi,
Sorry but I managed to try this only now. I've followed the instructions and the "Hibernate" button appeared in the interface, but when using it the system still did not restart with the hibernated session, even down at shutdown the screen flickered in the way I was used to with the previous PC.
Should I upload any logs to see what's the issue?
Thanks you!

It appears you were given information for hibernating to a swap partition. These instructions How to enable hibernation with swap partition on Linux Mint 19 have also worked for others using LM20. You can compare the steps you took to it to help troubleshoot your issue.

Hi, when i try this procdure i get as far as the command inxi -u and it just gives me this error Error 10: Unsupported value: missing required option(s) -j, -o, -p, -P for option: -l/-u
Check -h for correct parameters.

What do i need to do to proceed?
