It appears a successful hibernation followed by successful restore.
I have no idea what is going on. Did you report in Bugzilla?
Not yet.
I can tell you the same they told me once:
That looks like in https://bugzilla.opensuse.org/show_bug.cgi?id=1182346
Could you try hibernating directly via kernel interface: echo disk > /sys/power/state instead of systemd? If the problem is seen there, it's a bit easier to see what happening.
It didn't trigger.
mean it did not hibernate? Put that in the bugzilla.
The next step would be testing as described in Documentation/power/basic-pm-debugging.rst
I struck out trying to locate that document.
You need kernel sources installed. full path in my machine: /usr/src/linux-5.3.18-lp152.78/Documentation/power/basic-pm-debugging.rst I will attach and email it to you, off-list.
Then I asked on a forum: <https://forums.opensuse.org/showthread.php/556448-sleep-suspend-amp-hibernate-don-t-exactly>
By creating /etc/systemd/sleep.conf containing only
[Sleep] HibernateMode=shutdown
I am able to manually suspend or hibernate, but none of the power saving functions controlled via systemsettings5 in Plasma have any effect.
I never hibernate that way, in my case using XFCE. I always hibernate via command as root. Look, yesterday I closed the lid in my laptop. It went black, but did not suspend. I did not notice. When I came back to the room, the machine was alive, and a prompt was asking permission to hibernate, please give root password - because something or other was active. This bug has been active for many years. So, lesson: always suspend or hibernate as root, via command line.
I find it seriously disappointing that I can't find anything about power saving options in YaST.
They never were, AFAIR. -- Cheers / Saludos, Carlos E. R. (from 15.2 x86_64 at Telcontar)
