Ubuntu 14.04 - sudo pm-hibernate doesn't work

Question

There are a bunch of questions on here about suspend resume error.

The same question appears in: suspend/resume failure but I don't understand any of the responses. We are using different laptops (mind is Lenovo) so there may be different types of hardware that are effected.

I tried reading this tutorial. In my case sudo pm-hibernate does not work in the Terminal, and the configuration steps does not fix this.

I am trying to understand why Hibernate is going wrong, including the discussion power management/hibernate from the Ubuntu manual. They suggest there is a problem with swsusp but I am not sure how to tamper with that section.

I found GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" in my /etc/default/grub file.

Did anyone get this to work?

In fact head /var/log/pm-suspend.log leads to

Running hook /usr/lib/pm-utils/sleep.d/000kernel-change hibernate hibernate:
/usr/lib/pm-utils/sleep.d/000kernel-change hibernate hibernate: success.

Running hook /usr/lib/pm-utils/sleep.d/000record-status hibernate hibernate:

Answer 1

I was having the same problem.

sudo pm-hibernate

...nothing.

...nothing.

Looking around, I found a suggestion to check the pm-hibernate log:

>~$ head /var/log/pm-suspend.log

Ah! So the system needs to be rebooted because there was a kernel update. It would be great to get some kind of notification of the fact, instead of ...nothing.

BTW, to tell if you need to reboot:

>~$ ls -l /var/run/reboot-required
> -rw-r--r-- 1 root root 32 Apr 29 18:28 /var/run/reboot-required

Basically, if that file exists, a reboot is required. I can't tell you what will happen if you put the system into hibernation if you need to reboot due to a kernel update, but I was able to hibernate immediately when I did this:

>~$ sudo rm /var/run/do-not-hibernate

Answer 2

did u try to specify correct swap partition as mentioned in swsusp troubleshooting in PowerManagement/Hibernate? it fixed pm-hibernate for me. also, i use shutdown mode. I have lenovo z50-70.

My grub file has "quiet splash" too but I simply appended my swap partition beside it.
