Hibernate does not restore session

Hey
. I use a MacBook Pro Late 12, Ubuntu 18.04, i3wm and I have configured 12 Gb of swap (thats 1.5x my RAM size).

Unfortunately when my laptop tries to hibernate (like with sudo pm-hibernate) it just turns off completely and when I boot again it does not restore the session. I tried out several things, I even installed Manjaro in dual boot, but its just the same in manjaro. I could post a lot of my outputs, but I don't know which is important. I can easily add more stuff if requested.

Code:

G'day @Tillus and welcome to linux.org :)

Can you please give us the output of (a hash precedes my comments, not commands):

Code:
cat /etc/default/grub

# and

cat /etc/fstab
Cheers

Yeah sure, thanks for tuning in.
Code:
~$ cat /etc/default/grub

# /boot/grub/grub.cfg.

GRUB_CMDLINE_LINUX=""

~$ cat /etc/fstab
# /etc/fstab: static file system information.
#

# that works even if disks are added and removed. See fstab(5).
#

# / was on /dev/sda5 during installation

# /boot/efi was on /dev/sda1 during installation
UUID=67E3-17ED  /boot/efi       vfat    umask=0077      0       1
# swap was on /dev/sda4 during installation

So quick explanation: The default was #GRUB_CMDLINE_LINUX_DEFAULT="quiet splash". I read somewhere that I should put my swap as resume in there, so I tried it, but it did not change anything.

Haha, you were one step ahead of me :)

Tillus is this a dual boot with Mac OSX or is Ubuntu the only OS? Looks like it from the inxi output.

If the former, does hibernate work out of the Mac?

Oh, and perhaps a silly question, did you update grub following the change to /etc/default/grub?

Code:
sudo update-grub

Hey Charis,
thanks for your hint. I tried that out, but it did not change anything unfortunately.
@Wizard: I did update my grub before. What I also did is `sudo update-initramfs -u -k all` after I put `RESUME=UUID=43766461-abe9-4c26-bae0-1bfa64e85c2e` in `/etc/initramfs-tools/conf.d/resume`.
Yes I had macos also on my machine but somehow I killed it. :( Because I wanted to try out manjaro on my machine (in which hibernate also not works) I shrinked my macos partition in macos, but after the reboot I could not boot into macos anymore. But as I remember did hibernate work just well in macos.

Thanks, you guys also have a nice day!!:rolleyes:

OK, thanks for that. Next up is output for

Code:
cat /sys/power/state
I'll explain what I am looking for here, rather than just having you robotically follow orders :)

With the df -Th command, I was establishing that your Linux is using the "usual" EXT4 file system, rather than say BTRFS, often used with RAID systems and other (which does not support suspension).

swapon state was to see that it is on, else we would turn it on.

blkid established that the UUID for the partition was that of your Swap partition, not of your root partition, which is the one your OS is on. Hence the details in your /etc/default/grub are correct.

The command in this Post is to establish that your kernel supports hibernation, and via what methods.

Cheers

Wiz - I have a road trip today, so may be unavailable for some hours.

Yo, ok good to know whats going on :)
Code:
~$ cat /sys/power/state
freeze mem disk
So I guess hibernation should be enabled for my kernel via freeze.

Enjoy you road trip! I will sleep now for some hours so I'll be unavailable as well. ;)

Hey,

I really though I had made that final post. :rolleyes:
I just want to explain for future readers what solved the problem for me: I actually just installed a clean version of Manjaro i3 (therefore I had to delete my whole macos and any other OS) on my machine. And voila, now it works. Still do not know exactly what the problem was, but found a fix :)

I've never liked hibernation in any OS. Suspend to RAM does the job a lot better and in Linux case, it restores the session EVEN in the case of power loss. I stress on "even" because Windows loses everything stored in memory in case of power loss and one has to reboot it twice in a row in order to make it work again.

Maybe we have different definitions for different words, but in my case the normal suspend to ram is not saving the state on powerloss (and additionally consumes like 10% of battery over night). Otherwise I would not need hibernation as well :D

This may depend on the distro or on the power settings or even on the fact that it's a laptop. On the computer in my signature so far almost every distro I have tried restores session after power loss. Only about Arch IDK whether it does because I never got this far with it.
