Hibernation issue after resume

michele_deb · 01-11-2018, 11:00 AM

Dear,
I have an HP Notebook, model DV76190SL (from 2011) with Ubuntu 16.04 installed (dual boot with Windows10) and the following features:

The problem is the following:
after hibernation (using the menu for turn off the notebook or the command sudo pm-hibernate in a terminal) at the time of resuming I get a black screen, even though the fans work, and I am forced to restart Ubuntu because I am not able to return to the "saved state".
I have updated my Ubuntu yesterday using Ubuntu SW Center (I think the kernel has been updated).

In the file:

Quote:

logind.conf

in

Quote:

/etc/systemd

I have the entry

Quote:

HandleLidSwitch=hibernate

The current kernel is:

Quote:

uname -a
Linux michele-ubuntu 4.13.0-26-generic #29~16.04.2-Ubuntu SMP Tue Jan 9 22:00:44 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

Please, can you help me?
Thanks a lot.

the first two answers have been edited in 2017, so should still be valid.

Thanks a lot ondoho,
but after following the instructions on the page you have recommended, I still have the problem. Moreover, the content in

Quote:

/etc/polkit-1/localauthority/50-local.d/com.ubuntu.enable-hibernate.pkla

on my ubuntu, already had that entries (so, I just copied again to make sure I am not wrong!).
I am going crazy!
(Should I renounce, disactivating hibernation, and have just suspension?)

ondoho · 01-12-2018, 01:27 PM

^ sorry, i'm not fully familiar with the solutions offered there.
can you please walk us through what you did there, and how exactly the problem persists?

Thanks for your help ondoho.
Some days ago, I tried to solve the problem of hibernation and, on several pages on web, the proposal was to edit the content in:

Code:

/etc/polkit-1/localauthority/50-local.d/com.ubuntu.enable-hibernate.pkla

. I suppose this has to be done to "activate" hibernation. Now, in the menu (on the right top) for shut down Ubuntu, I can see the hibernation option, but if I try to hibernate, when I try to resume Ubuntu, I get a black screen and I cannot do anything. The command

Code:

sudo pm-hibernate

works, but when I try to exit from hibernation I cannot back to the "saved state" as I expect.
Furthermore, the issue rised up after an update done through the Ubuntu SW Center.

I hope I have been more clear.

ondoho · 01-14-2018, 03:12 AM

i am unfortunately not very good with ubuntu.

looking at that askubuntu article, have you

run update-grub afterwards
is your swap partition large enough
you have to test with 'sudo systemctl hibernate' - testing includes reading the output received closely - in this case, it would be 'systemctl status hibernate.target' or something, after rebooting

thishttps://help.ubuntu.com/stable/ubunt...hibernate.html seem to be the authoritative answer. be sure you addressed ALL points therein, then if it still doesn't work, move on to "See also".

I appreciate a lot your effort ondoho!

So, swap size is:

Code:

free -h
              total        used        free      shared  buff/cache   available
Mem:           7,7G        1,1G        5,5G        236M        1,1G        6,1G
Swap:          7,6G          0B        7,6G

Test done with 'sudo systemctl hibernate', but failed to resume after rebooting (black screen and nothing I can do)

I followed all steps indicated at that link. Even edited (again) the

Code:

etc/polkit-1/localauthority/50-local.d/com.ubuntu.enable-hibernate.pkla

file, but I still can't resume after hibernation.

What is your current kernel version?

Code:

uname -r

The latest supported version, so no problem there. Thanks.

This issue may well be related to your graphics hardware. I note that you appear to have hybrid (Intel/AMD) graphics hardware. Which drivers are you using?

Yes, hybrid graphic (Intel/AMD).

Code:

michele@michele-ubuntu:~$ sudo lspci | grep -E 'VGA|Display'
[sudo] password di michele:

michele@michele-ubuntu:~$ sudo lshw -c display | grep driver
       configuration: driver=i915 latency=0

The weird thing is that the issue came up after an update by Ubuntu SW Center done some days ago. Is there a way to check which update have been istalled? I would say a report or something similar.

I'm not an Ubunu user, but just in case the following is helpful to you:

ferrari · 01-15-2018, 04:39 AM

To get hardware and driver info use

Code:

sudo lspci -nnk | grep -EA2 'VGA|Display'

It may well be a kernel regression.
