Hibernation does not work

[miggoycor]

When I press hibernate, the machine seems to respond and power down. However, when I resume, it turns on normally, as in it was booted, not hibernated. Nothing was saved and Mint started a new session. It did not even remember it went on hibernation. I made sure the amount of active RAM was less than the amount of the Swap Partition, but nothing was saved, apparently.

I have 2 gig ram and 2 gig swap.

I am using Linux Mint 14 Cinammon.

It's been a really long time since I had to deal with the suspend/hibernate issues. I put together a small paper a while back dealing with the topic in Mint Debian. I'm not certain if it applies to your situation. Suggest taking a look at the paper and see if the resume is set properly. If not the paper should address how to fix it.

Hope this helps.

It seems to me, that the resume-partition is not set on installation. You have to edit /etc/initramfs-tools/conf.d/resume

Code: Select all

RESUME=UUID=<swap_UUID>

where <swap_UUID> has to be the same as for the swap-partition in your /etc/fstab
After editing /etc/initramfs-tools/conf.d/resume you have to run

Code: Select all

sudo update-initramfs -u
