You wrote /dev/sda1 instead of /dev/sda2 in /etc/fstab. Also you (used to?) have your swap encrypted what does not allow (at least not naturally) hibernation. Edit /etc/fstab to remove the line "/dev/mapper/cryptswap1 none swap sw 0 0" and to turn "/dev/sda1 swap swap defaults 0 0" into "/dev/sda2 swap swap defaults 0 0" (here using the GEdit text editor):
$ gksu gedit /etc/fstab
Save the file and run this command to enable swapping:
$ sudo swapon -a
This command will tell if your swap aws really enables:
$ swapon -s
