[gentoo-user] hibernation

[gentoo-user] hibernation

[Michael Vetter]

Hello there,

I use i3 as my window manager and use xfce4-power-manager for saving
battery and stuff on my laptop. Today I tried "hibernation" for the
first time and realized: it does not work.

All I did so far was installing fce4-power-manager selecting some
sections in kernel config that seemed necessary and installed polkit.

However when I close my notebook's lid (I configured xfce4-power-manager
to switch into hibernation in this case) it shuts down, but when i press
the start button, it just does a normal restart.
What am I missing?

Michael

Maybe you need to pass the resume-partition parameter to the kernel in the
bootloader. Point it to your swap device.

You can boot normal with this parameter set and not hibernated

To test hibernate try the following:

1) Stop all important stuff
2) run the following as root:
#  echo disk > /sys/power/state

If this works, then you can try to configure a power management tool. 
Please also ensure you only have 1 power management tool configured.

Do you want to configure

a) simply hibernation, which means that the RAM is still powered by your 
battery and just the rest of the computer is being switched off (CPU, 
HDDs and so on)

or

b) suspend to disk, which means that the whole content of the RAM is 
being written on your HDD and after that your computer is being shut 
down entirely?

Maybe I should add: I have EFI notebook, and my kernel is copied to
/boot/EFI/Boot/bootx64.efi. So I boot over that EFI thing because it
seemed the easiest thing to set up..

Yes, thats what I want to achive.

You can set the resume partition in the kernel. Might be an option.

Did you try suspending using the echo command I mentioned earlier?

Okay, so I changed my kernel command string from "root=/dev/sdb2" to
"root=/dev/sdb2,resume=/dev/mapper/g-SWAP".

Then typed your suspension command again, now the system isn't booting
up anymore: kernel prints trace.

In my menuconfig I have a space separated list, not comma separated.
So I guess the boot failure is, that the kernel can't find the root
partition /dev/sdb2,resume...

Okay, sorry thought this is equivalent to [1].
Anyways, I changed it to space and my system boots now.
So I tried the suspend command again, but when rebooting its like a
fresh reboot.

Any ideas?

Yes.
If using LVM for the swap partition (and subsequently the resume) you need to use an initramfs.

I will dig out the script I use on my laptop and post it tomorrow. (It boots faster with a custom script compared to the genkernel or dracut ones)

The sad thing about hibernation is, that it has always kinda been some 
kind of lackluster in the kernel and quite disappointing. It is a kind 
of area which does not get much love in the kernel for at least over one 
decade.

he number of computers it does not work is bigger than the number of 
computers it does work on correctly.

At least last time I tried it it was quite like that. Hibernation is 
disabled by default on Ubuntu 14.04, because it is so unreliable and 
broken.

In fact, there are three different kind of implementations around namely:

a) the thing in the main line kernel, which seems to work quite subpar, 
which is being used by the utility swsusp,
b) something in the user space being called uswsusp,
c) and an alternative implementation for the kernel being named "Tux on 
Ice."

Many do consider Tux on Ice the most reliable way to get hibernation up 
and running on Linux, unfortunately development seems to be stalled 
since always about one year and it is not part of the main line kernel.

So if you want to get this working reliable, good luck. You'll need it.

Hibernation depends on a myriad of CPU variants, setting and the matching
memory issues. (U)efi is a good place to start your long, arduous journey
of research [1] ; see S4.


I would research the problem and fix it with winblows as the operating
system, if possible; then hope that those setting are not changed
by booting linux. Often you can copy the bios setting from the laptop
and find tools to at least view the contents legibly. It does depend
on the bios. Maybe you need a vendor supplied bios update/downgrade.

Maybe Coreboot, has some old work laying around that is relevant to
your needs [2]. It is mostly a research journey, that may lead
to success or failure. Hard to say, as sometimes the same make and 
model of a laptop, has diffent internal components (like firmware, bios
and chips)...


Good hunting!

Bit later then planned.

The "init" file is the initramfs init-file.
The "config" is what I configure in the kernel:

$ zcat /proc/config.gz | grep initramfs
CONFIG_INITRAMFS_SOURCE="/usr/src/initramfs/config"

There are a few changes you'll need to do:
1) In the "init" file, change the name of the swap-partition you use
2) In the "config" file, change the following paths:
  - init-file
3) In the "config" file, run the command mentioned at the end of the file and
    add the result of the command to the end of the " config " file.

I have been using this config succesfully for over a year on my laptop.

Not my experience, suspend-to-disk works quite well. The biggest issue was 
with certain drivers not being able to re-initialize certain hardware. (Yes, I 
am talking about the likes of Nvidia)
With current kernels, it does work though.

For suspend-to-ram, I agree.
Suspend-to-disk can be handled by the OS.

It is not just Nvidia.  Suspend to disk (hybernation) worked fine on my laptop 
for years.  Then something changed in the kernel and now although it will 
hybernate, waking up causes all sort of failures and crashes.  It is a kernel 
bug, I found out that someone reported it last year, but it has not been fixed 
yet it seems.

On another PC both hybernation and sleep have gone through a cyclical pattern 
of working or not working over the years.  Thankfully now they are working!

I had a similar experience and found it as caused by the ethernet driver.
I added a line to my hibernate script to unload the module before
hibernating and the problem went away.
