I have tryed to hibernate Kubuntu lucid lynx but was unsuccessful, after short seekin/googlin I have found a solution:

It seems that there is still old uncomplete fix in lucid?

sorry this should be posted in lucid subtree....

Re: Hibernate

Hi

Have you got a swap partition and is it at least the size of your RAM as without it you will never be able to hibernate?

No, in kubuntu default config settings it cannot hibernate, because of /sys/power/image_size, which is reporting a need to allocate an image with a size of ~500Gb, and this overlimit of my drive (160Gb only) at all.

As expressed in a topic (included above) echo swapspaceinkbytes > /sys/power/image_size will solve this problem, and I just have used rc.local to supply echo... into this a value of proper size for hibernate image.

I am not sure at the moment, but at least in lucid this /sys/power/image_size should be corrected to provide clean hibernate procedure. Currently it is errorneus, and looks like a mistake.

BTW, I use linux-preempt kernel.

update: sorry, changed to swapspaceinkbytes, my typo.

Are you sure you are reading the figure correctly? In my Lucid 10.04, the size is approximately 525Mb:

cat /sys/power/image_size
524288000

Yes, your supposition is definitely straight - I have 1,2Gb for swap and usually 200Mb is used on it, plus 400Mb inmemory workingset. But with the default value you have quoted my lucid does not hibernate. Not enough in dmesg output

I have used instructions from the link I have attached in my first post, It seems that the value of 524288000 is in kb indeed. At least used by hybernate as kb, not bytes.

Perhaps there is a mistake inside lucid config, hibernate support, or kernel itself, I dont know, but setting this to the value taken from `free` (available swap space in kb) makes hibernation work.

So, I suppose that /sys/power/image_size is expressed in kilobytes rather than bytes. And I am not sure that I am right here.
