Hibernation option has been available at the press of the power button on my netbook running Ubuntu 10.04. I lost it after resizing partitions and I'd like to have it back.
The steps leading up to the loss of the hibernate option:
I made an image of my 32 GB SSD with Clonezilla, replaced the SSD with a 64 GB drive and restored the image to the new drive. After I restored the image the hibernate option was still present and functional.
But, since I cloned a 32 GB drive to a 64 GB drive, the boot partition ended up being smaller than 32 GB and almost half of the drive was unalocated. Using Gparted I deleted the cloned extended and swap partitions, resized the boot partition, and created new extended and swap partitions. In my first attempt I made an error and made the swap partition smaller than my RAM. When I booted in 10.04 I realized the hibernate option was missing.
Then I went back to Gparted, resized the swap partition to more than twice the size of my RAM and the hibernate option was still missing.
sudo pm-hibernate shuts down the network, flashes the screen black but then wakes up a split second later without me touching anything. I have a feeling that starting Ubunutu with the swap partition too small for the RAM has reconfigured something.
sudo fdisk -l gives:
