How to enable hibernation with swap partition on Linux Mint 19

[ngiampaoli]

Thank you for the tutorial
It works great.

Just a question: why would anyone to enable hibernation? It's a too slow process to be useful.

Not really, only takes seconds, in particular with an SSD. Depends on what you do with your machine but for me it's certainly faster than closing everything down, saving every document, and re-opening it all again next time you start the computer. It's been my default for years on both Linux and Windows machines.

Nah, I don't close anything. Just suspend it to RAM. Takes 2 seconds to powerdown/wake up.

Sure, you could also just leave it running, but neither of those solutions actually turns your computer off to the point where you can cut the power.

Maybe I should have clarified that in my original response: I want to turn my computer off.

Exactly. Although I use suspend (sleep) by default on my D255E netbook, Hibernate is an essential function in the event of low or critical battery levels when one can't access a mains socket. Especially so with the Dell (server machine) in case of a power cut, as its battery is well past its use-by date.

Suspend / sleep still drains the battery, albeit rather slowly, meaning the Acer has to be plugged in when I get home in order to avoid unnecessary battery wear.

Hello,

I am sorry to say this doesn't work for me. I do get the button but hibernation does not work at all.
I have been running LMDE2 for more than one year and then decided to move to Mint 19 to get newer software. LMDE2 with kernel 3.16 had some glitches but in the last 6 months hibernation worked like a charm. I tend to believe the problem is in kernel 4.15, because all I get is freezing the machine in a coma state, when I have to push the power button to kill it. When rebooting, the system has a fresh start. Remembering what the disk activity was like in LMDE2 and checking what it is like now, I would say the hibernation process never writes a single byte to the swap partition. Of course I put the UUID of the swap partition (checked also by GParted) into the grub file. I would appreciate suggestions, here below is the output of /var/log/pm-suspend.log. Thanks in advance

EDIT I installed stable kernel 4.9.124 and hibernation works flawlessly again. Although I really don't feel expert enough to point fingers, it looks that in this respect there's a regression in the kernel between 4.9 and 4.15, which might affect only some machines.

mar 28 ago 2018, 20.24.33, CEST: performing hibernate

[xGuy]

Many thanks for this excellent HowTo which worked fine for me on Mint 19.

One issue I hit was that when restarting from a hibernation, the GRUB screen had a 30 second timeout rather than the 3 seconds I had set.

After a little investigation I found that inserting the following line into /etc/default/grub fixed this :-
GRUB_RECOVERYFAIL_TIMEOUT GRUB_RECORDFAIL_TIMEOUT=$GRUB_TIMEOUT

This might be down to my environment which is an Asus EeePC Netbook used as a Media Server. The internal HDD layout is as supplied with Windows XP with a standard Windows MBR. Mint 19 is installed on a USB HDD with GRUB2 on its MBR. So booting Mint19 involves pressing ESC a couple of times to get the USB HDD in the Boot Device List.

This set up was simply to prove that Mint 19 64 bit Cinnamon with Wine could run an old version of iTunes just as well as Windows XP can. Which it does (although 1GB RAM is a bit tight).

I believe you mean GRUB_RECORDFAIL_TIMEOUT ?

[xGuy]

Many thanks for pointing out that serious error! It could potentially have caused a lot of wasted time for someone.

I will try to be more accurate in future. Normally I would copy paste from the actual file but in this case I couldn't do that - not even if logged in remotely via VNC. I guess I could have pulled the file over with SSH.

Apologies to anyone misled but hopefully your timely intervention will have forestalled that possibility.

1a. Copy your UUID of the swap partition from fstab:

Code: Select all

cat /etc/fstab

1b. Add the boot option to grub (your boot loader):

Code: Select all

xed admin:///etc/default/grub

Add the following boot option "resume=UUID=putYourSwapUUIDhere" to GRUB_CNMDLINE_LINUX_DEFAULT.
Example:

Code: Select all

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash resume=UUID=putYourSwapUUIDhere"

Note that you have to copy your UUID from fstab to replace putYourSwapUUIDhere.

Save the grub file and update grub:

Code: Select all

sudo update-grub

instead of the uuid, i had to add the mount point. which for me was:

Code: Select all

/dev/mapper/mint--vg-swap_1 none

this is probably because i have an encrypted file system with lvm. other than that, excellent howto, thank you! i don't like to reboot that often because i like to keep applications open. also, hibernation keeps encryption intact, good thing.

[IC4]

I've done what the tutorial suggests. systemctl hibernate + restarting is same as shutdown and restarting.
I know the machine can hibernate since Ubuntu 16 used to do that, and win10 still can.
secure boot is disabled.
I'm losing my mind.
I tried with swapfile at first, reinstalled mint altogether to make a swap partition, I wish to love linux again, please help me not to give up on it :-}

You can also hibernate with a swap file, this is just not the thread for that.

I know the machine can hibernate since Ubuntu 16 used to do that, and win10 still can.

And yet neither of them are Mint 19. Just because another operating system can hibernate that doesn't mean that your current one can. Hibernation issues are usually because of drivers, and those depend on firmware and kernel primarily. Your log files may provide information on where the problem lies exactly. Although your problem description makes it just as likely that you simply made a mistake. Please discuss the details in a thread of your own though.

Just an addition to the discussion, you would want to make sure your BIOS/UEFI is set to use the S3/S4 state if compatible, using power management scheme ACPI stuff. Some older hardware might not support it, or might not have it configured for use.

If default mode is S1 and the motherboard is not even capable of S4, or it is not authorized to use S3/S4, then full hibernate will surely not be able to work.

I'm just guessing that any modern pc, and especially laptops will have these settings appropriately capable and configured, but not necessarily on older desktops for sure. So, just have a check in the BIOS.

If you can only get S3 then you will only be able to suspend instead of hibernate.

Hello,

This is my partition setup as per gparted

Can I setup my Linux Mint 19 installation to hibernate using this guide?

Thanks.

[BG405]

Can I setup my Linux Mint 19 installation to hibernate using this guide?

As I use swap partitions on my systems, rather than a swap file, I may not know the answer to this as I don't know how swap files are handled; however, the output of your cat /etc/fstab will help determine this. It may well be useful/informative to post this anyway. Must do a bit of reading. I do know hibernation is possible with a swap file, however this info will show if it's an easy fix, which I suspect it may be.

[karlchen]

Hello, fkasmani.

Can I setup my Linux Mint 19 installation to hibernate using this guide?

Your gparted screenshot shows that there is no swap device on your system.
This tutorial thread, however, explicitly tells "How to enable hibernation with swap partition on Linux Mint 19".
As a consequence, you cannot follow this tutorial in order to enable hibernation on your system.

But this guide might be what you need: [GUIDE] How to hibernate to a swap file in Linux Mint 19.x. Provided your system uses a swapfile.

Best regards,
Karl

[gm10]

I don't know how swap files are handled; [...] Must do a bit of reading. I do know hibernation is possible with a swap file,

Start by reading the second sentence of the OP. SCNR.

[BG405]

@gm10: Yes, somehow I missed that .. looks like fkasmani did too. Don't know what "SCNR" means? I'm often distracted, though, and have a useless short-term memory.

[TI58C]

Hi all,

This may be a very "noob" question, but

I use a hp probook 6750b with mint 19.1. and have 8G swap-partition. Installed the old-fashioned way (done before reading about swap-file).

When I close the laptop, everything goes down. USB-sticks are powered down and can be safely removed.
After re-opening, have to hit power-button to start again. Back in a second.

To me this looks/feels like hibernation. But is it ? It works like this "out-of the box". Am I just lucky or am I confusing hibernate with something else (sleep?).
