Hibernate not saving any session data

[xmen123]

what worked for me
1.- Copy the UUID number series of your swap
$ cat /etc/fstab
UUID=XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX

2.- Edit the file / etc / default / grub and look for the line
GRUB_CMDLINE_LINUX=""
within the "" sticks the UUID swap series thus remaining
GRUB_CMDLINE_LINUX="resume=UUID=XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX"

3.- Update the grub
$ sudo update-grub

4.- Check the file "resume" is the same as the UUID of your swap
$ cat /etc/initramfs-tools/conf.d/resume

5.- update the initramfs
$ sudo update-initramfs -u

6.- Restart


Note: it works on touch
the only inconvenience that I see is that once hibernated when resume does not ask for the password of the user, that picardia  ;D
