[Solved]Restart after hibernation does not work (Mint 17)

[nonymous]

Hi,
After having found some posts on this forum dealing with the almost same issue, I could not fix mine.
On my laptop, I was on Mint 16 Xfce without any problem with hibernation.
I switched 3 days ago to Linux 17 Cinnamon (fresh install).
Everything works fine, except hibernation and suspend.
The PC powers off correctly.
When I restart the computer, the graphical session starts, showing the current time, but I can't do anything : no login prompt, no mouse cursor.
CTRL+ALT+Backspace does not restart the X session.
CLTR+ALT+F1 switches to text session, but I can not login.

I've found here an advice to disable hibernation after the install of Mint 17.
W T F ?
Why would I do that ? Hibernation is really usefull.

What could I do please ?
Thanks !

Hi,

let's have a look at your system

Code: Select all

sudo inxi -U

Code: Select all

inxi -Fxz

and off course it has the latest updates?

[nonymous]

Hi PatH57,

My system is up to date (I checked that yesterday).
I also updated the kernel to the last version.

I'll try to post the results of the inxi commands tonight.

Thanks

Here is the contents of /etc/initramfs-tools/conf.d/resume :

Code: Select all

RESUME=UUID=53a799e8-037a-46b6-bf76-59ea093ec261

And here is the output of blkid -o list :

Code: Select all

device                              fs_type       label          mount point                             UUID
---------------------------------------------------------------------------------------------------------------------------------------------
/dev/sda1                                                        /boot                                   
/dev/sda5                                                        (not mounted)                           
/dev/mapper/sda5_crypt                                           (not mounted)                           
/dev/mapper/mint--vg-root                                        /                                       
/dev/mapper/mint--vg-swap_1                                      <swap> 

Is it normal to have a difference between the UUID in the resume file and "/dev/mapper/mint--vg-swap_1" ?

[PatH57]

did you encrypt something? It does happen that it won't work especially if the swap is encrypted also ?

[nonymous]

Hi,
Yes I have chosen the disk encryption during the installation.

[PatH57]

try this but I never could get it to work so I disabled hibernate and just use suspend (with an ssd drive my bootup is even faster then coming back from hibernate)

[nonymous]

Hmm sorry, what should I try ?

[PatH57]

sorry forgot the link.

[nonymous]

Hi, thanks for the link.
I've read the article, but I don't feel confident about the things to do (one is for ubuntu and the original post was about older versions of mint ).
It seems that the issue has to do with the disk encryption, so I'm planning to do a new fresh install, without encrypting the full disk but only my home folder.
I just hope that it will fix the hibernation problem.

It's just surprising that a function that worked fine in the previous version does not anymore (my previous Mint installation had also a full disk encryption).

[PatH57]

it's more related to the fact that the hibernation does vary depending on the manufacturer so at some stage Debian and Ubuntu dropped the ball a bit (it's no longer enabled as default on Ubuntu 14.04 and Mint 17)
Let's see how it goes without swap encryption..

[nonymous]

Juste in case, do you know if I can test it using an usb key with the live cd of Mint ? Would it be relevant ?
If I could avoid to erase all my system, it would be nice...

[PatH57]

it won't work on a live session as hibernate has to write to the stick and swap off course is not "persistant" on a live session...

[nonymous]

Damned, off course !
OK, I will try with another hard disk.

I will complete this post after my tests.

[nonymous]

Hi,
I am really disappointed. Here is what I have tried :
- install Linux Mint 17 Cinnamon without disk encryption : resume from hibernation failed
- install Linux Mint 17 Xfce without disk encryption : the system does not power off when I try "Hibernate"

I have tried some tricks (from this site), like :
- editing the "GRUB_CMDLINE_LINUX="resume..." part in the grub config file
- removing hibernate uswsusp

My last idea is that I may have not enough swap, so if I'm really motivated I will try to reinstall Linux Mint 17 Cinnamon with default partitionning then repartition to add more swap. Dangerous and boring.

If I'm not motivated, I will try another distro... Ubuntu maybe ?

Anyway, this issue makes me insane... I really need to have hibernation working on my laptop, I really like to use Linux, and I really don't want to go back to Windows...

I've found a lot of posts dealing with hibernation problems and I'm surprised that such a standard functionnality can't work easily here.

[PatH57]

I'm surprised that such a standard functionnality

that is the problem, it's not standard each laptop manyfacturer has used a "different way to implement it.
Off course because they do have to provide correct drivers for MS it kind of works most of the time, however the open source world has a harder time finding out the right settings (Debian and Ubuntu dropped the ball on it that's why it is disabled as default for the time being)

[nonymous]

OK, I understand the problem with the heterogeneity of the hardware.
Regression (from LM16 to LM17 in my case) is more surprising.

What do you mean by "Debian and Ubuntu dropped the ball on it" ? Did they officially announce that hibernation was an abandoned functionnality ?
(In Mint 17, I did nothing special to activate the "Hibernate" function, it simply does not work).

I don't know if it's worth looking for a solution (that means spending time and losing nerves).

[PatH57]

that's kind of the easy way to check it the default settings (my cinnamon doesn't like it so I just use suspend)
or

[nonymous]

Thank you, I'll check that.
I hope I'll find a solution...
