hibernation with 12.04 wubi - any way?

You can hibernate with a swap partition (basic steps outlined here: http://ubuntu-with-wubi.blogspot.ca/2011/01/swap-and-hibernation.html ). But if you decide to create a swap partition then I'd recommend just moving to a normal dual boot. Wubi works great for trying out Ubuntu, but I wouldn't rely on it as a production OS (if you do make sure you keep current backups outside of the virtual disk (on /host or an external drive, or in the cloud).

Thank you for the links and advices, I followed your recommendation to move to a dual boot:
I used your script to move the wubi install to a new partition, also created a swap partition, and got the grub..
It took some time, but everything seemed to go well. Ubuntu booted from the new partition.

Unfortunately, the Windows data were not accessible anymore. I solved that by editing fstab.
More difficult is that I can no longer boot Windows, it directly starts up Ubuntu.
I guess, grub starts from the small recovery partition at the very beginning of the drive, and does not see Windows on the second partition.

So far, I could not test the hibernation. I tried s2disk, but got an error message about the swap being not accessible.

Any ideas or links which can help me here?

P.S.: the message from s2disk was: "Could not use the resume device (try swapon -a). Reason: No such device"

I recommend running the bootinfoscript and posting the RESULTS.txt on pastebin, then copying the pastebin link here. You can get the bootinfoscript at http://bootinfoscript.sourceforge.net/
(Note: the instructions are a bit out of date in that link - it's "sudo bash bootinfoscript" (you need to drop the .sh))

That will help me see what is going on.

You can also try running the following to update your grub menu:
sudo update-grub
(but the migration script should have picked up Windows).

After that we can look at why the hibernation issue isn't working by posting the results of the following commands:
cat /etc/fstab

sudo blkid

cat /etc/initramfs-tools/conf.d/resume

(The first two commands will already be in the bootinfoscript so if you've posted that, just give me the last one)
Thanks

Thanks for replying so fast.
in short:
- pastebin link of the bootinfoscript results: http://pastebin.com/gUMjdCGu

- sudo update-grub did not change the behavior

- initramfs-tools/conf.d/resume: RESUME=UUID=bb326607-3cb0-49d8-8c2b-c5bbbd753f41

Because you set the Wubi install to be the default, it affects how Grub sees Windows. Grub is actually extracting it from the "Default" entry in the boot.ini, and since the default is "Ubuntu", that's what it displays.

So when you see: "Ubuntu (on /dev/sda2)" that's actually Windows, and selecting that will lead to your Windows boot manager screen with Ubuntu/Windows, so just select Windows from there and it should boot. Then go to your Startup & Recovery settings on Windows and change the default OS back to Windows, and then reboot into Ubuntu (migrated) and run "sudo update-grub" and it will change the menuentry to something like "Windows XP (on /dev/sda2)"

I'll post some more info on the hibernate thing soon. Please post the output of the following commands as well:

swapon -s

free

Thanks

I figure you have 3.45GB of Swap, so that should exceed the size of your RAM in order to hibernate.
You can look at syslog to see any error messages:
cat /var/log/syslog | grep PM:

Make sure you test hibernation using this:
sudo pm-hibernate

Don't use s2disk.

To enable the Hibernate option on the system menu refer to this:

Thank you! That's a nice feature of grub, very disturbing. I'll try that tomorrow morning (booting Windows takes long time).

For the boot issue, you were right. I started up the "Ubuntu (on /dev/sda2)" - and the Windows boot loader came up. Then changed the sequence in Windows, in Ubuntu updated grub.
The boot issue is solved. Thank you!

For the hibernation issue, it seems, the system does not recognize - or cannot access - the swap partition at the time almost everything else was shut down successfully.
The error messages in syslog (at start-up) and pm-suspend.log (at pm-hibernate) point to problems with the swap.
In Windows, a special hibernation file needs to be prepared in advance. How is that done in Ubuntu?

It is possible to hibernate with a swap file but it's not the supported way. I can point you at a howto, but can't help you with it beyond that since I've never tried it.

I know that you cannot hibernate with an encrypted swap partition (that doesn't seem to be the case here, and you'd know if it was). But other than that I can't understand why it wouldn't work... you have the resume file setup correctly, the swap is active, much bigger than your RAM, configured correctly in /etc/fstab - so this is puzzling.

After running "sudo pm-hibernate" please post the results of "cat /var/log/syslog | grep PM:" again.

If you've made any edits to /etc/default/grub please post that as well.

PS here is a link to that howto I mentioned - it appears to have been updated last in September 2011 - disclaimer: please don't take the posting of a link as a recommendation or any guarantee that it will work: http://ubuntuforums.org/showthread.php?t=1042946

Again, thank you for your time and efforts.
"you have the resume file setup correctly":
How to check that? I am not aware that I created/setup that resume file.

what I am concerned about is the entry in /var/log/pm-suspend.log: "No such device":

s2disk: Could not use the resume device (try swapon -a). Reason: No such device

I tried some grub settings using Grub Customizer:

I will also have a look at the link you gave me.

You posted the contents of the resume file:
 initramfs-tools/conf.d/resume: RESUME=UUID=bb326607-3cb0-49d8-8c2b-c5bbbd753f41

I'll have a look at this later today.

wow, it was uswsusp.
I installed it because it seemed to promise to be working with a swap file, like in a wubi installation. It did not work that way, and I do not have a wubi installation anymore.
I had it hibernate (save to swap and turn off) successfully, but the resume did not work, always resulted in a cold boot.

I purged uswsusp, and hibernation works now, including resume.
Thank you very much for your help!

Thanks bcbc, that solved my question.

Great... good work
