HOWTO: Use swapfile instead of partition and hibernate

[dralastair]

Just want to add I've got this working with Ubuntu 10.10 and ext4 filesystem on an eeepc 1005. I've got 4G swapfile (for 2G RAM) on root partition.
Suspend was working correctly prior to the mod.

I used the original HOWTO with RBertrand's update for grub2 and filefrag.

The only issue I'm noticing at the moment is that on resume the sound is muted - but that's something I can live with...

Update

Hibernate working fully now - had to install hibernate package:

sudo apt-get install hibernate

probably should have had this to start with!

Hi all,

I'm running ubuntu 10.10 which uses grub2 and I hope suspend to work with a swap file (read somewhere uswsusp is needed).

I suppose I need to edit /etc/default/grub before running update-grub. According to your instructions (thanks for such great tutorial) anyone knows how this file should be edited?

Thanks in advanced. Regards,

Jean Pierre

sorry I didn't notice that the thread was more than one page long Will check dralastair and RBertrand's posts in detail before asking something again.

(sorry for my previous repeated posts I had a bad connection and hit many times the "submit reply" button)

I'm exclusively running kubuntu 10.10 (maverick) on an asus N53J with a SSD of 120GB and 10GB of RAM, with a single ext4 partition (without swap partition which seemed a good configuration for my hardware). I followed the instructions found here to make suspend to a swap file work without success.

First of all I'm confuse about which suspend method to use: the in kernel default method (aka suspend or swsusp) or user space suspend (uswsusp). I tried both. I did it as follows:

1. swsusp

Followed the instructions here *without* installing uswsusp. To get the swap offset I ran: sudo filefrag -v /swapfile without problem. The output was:

Filesystem type is: ef53
File size of /swapfile is 5215938560 (1273423 blocks, blocksize 4096)
 ext logical physical expected length flags
   0       0 10649600            2048
...

I noted the 10649600 number. To configure grub2 (before running sudo update-grub, I changed the GRUB_CMDLINE_LINUX_DEFAULT variable found in /etc/default/grub. It looks like this:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash elevator=deadline resume=UUID=2e55de9d-891f-4040-b9a5-6c96b6bfb650 resume_offset=10649600"

Note: It's also possible to configure the variable GRUB_CMDLINE_LINUX in grub. In this case, the changes will affect also the "recovery mode" kernel images.

Then I configured the /etc/initramfs-tools/conf.d/resume and run sudo update-initramfs -u just as suggested here.

Result: suspend to ram works fine. Suspend to disk puts my screen to black and hangs. After some minutes I reset the laptop. I noticed that when hitting the power button the machine turned off with activity as if one has turned it off correctly.

2. uswsusp

I made the following changes respect to the previous method:
1. I installed hibernate and uswsusp: sudo apt-get install hibernate uswsusp
2. To get the swap offset I ran: sudo swap-offset /swapfile. The output was:

resume offset = 10649600

Same offset as in the previous case.
3. I then edit the /etc/uswsusp.conf file running sudo dpkg-reconfigure uswsusp. It looks like this:

# /etc/uswsusp.conf(8) -- Configuration file for s2disk/s2both 
resume device = /dev/sda1
compress = y
early writeout = y
image size = 4.79866e+09
RSA key file = /etc/uswsusp.key
shutdown method = platform
resume offset = 10649600
compute checksum = y
suspend loglevel = 5
max loglevel = 5

Before editing it, I was surprised by the fact that the file was already well configured (it had the correct offset. I just ended adding the log entries to it).

Result: same as with swsusp. I also tried to integrate uswsusp with pm-utils without success as explained here (seems that swsusp installation routine already does it).

I thought I couldn't get the laptop to hibernate because selecting "Hibernate" from the shutdown menu only brought up a gray screen. However, I found the the command "sudo hibernate" from a terminal DID put it into hibernation.

How do I get it to work from the menu?

p.s. Selecting "Hibernate" from the shutdown applet causes a blank gray screen to come up for several seconds, then the computer goes off. Next boot goes through normal start-up to login-screen.

Selecting "Hibernate" from the indicator applet first brings up a locked-screen password entry, then shuts down. Next boot goes through normal start-up to login-screen. However, after login, network starts out disabled (?).

Can't seem to get this working on my fresh Maverick install.

Tried all the suggestions in this thread, but none helped unfortunately. Even removed all (non-essential) pieces of hardware, without success.

The swsusp method does shutdown, but is unable to load the image.
In my boot.log I found the following:

Invalidating stale software suspend images... /swapfileswapon: /swapfile: software suspend data detected. Rewriting the swap signature.

The uswsusp method saves all the data to the swapfile, but goes straight back to login screen or the open session, depending on how it is called.
I couldn't find any errors in dmesg between the process of shutting down devices and starting them again:

I also tried tuxonice, which didn't work right away. Since I like to use rt-kernels sometimes, i guess it wouldn't be a solution for me anyways.

Any suggestions on what else there is to try?

Thanks for mentioning the quirk-checker.sh script. It worked for a friend of mine on a new Sony VAIO with two SSDs, but my MacBook Pro is still without hibernate, after all these years.

From the man page on uswsusp:

resume offset
Necessary if a swap file is used for suspending. In such a case the device identified by the "resume device" parameter is regarded as the partition that contains the swap file, and "resume offset" must be equal to the offset from the beginning of this partition at which the swap file's header is located, in <PAGE_SIZE> units. The value of this parameter for given swap file can be determined by the swap-offset program (has to be run as root) included in this package. [For this feature to work, you will need an -mm kernel, 2.6.18-mm3 or newer.]

Most unfortunate. For those not familiar, the -mm tree is no longer maintained, not since 2007. Given that the hibernate command just calls other scripts, this would explain why hibernation isn't working, even with a properly configured uswsusp.conf. Found this bug report interesting, particularly comment #6.

Hate to be pessimistic, but I'm near giving up on this s2ram works OK, but I've never had s2disk working on this laptop.
