Mageia forum

On a desktop computer I have installed Mageia 8 with Plasma. I can put the computer into hibernation mode. When I want to start the computer from hibernation, it restarts completely instead of starting from hibernation. Accordingly, the programs and windows that are open in hibernation are no longer active. - The Standby function works fine (set to standby and restart from standby).

How can the hibernation problem be narrowed down?

The following information about the computer

Thanks in advance

This is mentioned in the Errata: https://wiki.mageia.org/en/Mageia_8_Errata#Hibernation

Thank you for the hint and the link.

Will this be fixed so that the hibernation mode works automatically again and if so, when?

As mentioned in the bug and in the errata, this is an UPSTREAM bug. That means Mageia have to wait until the developers have fixed this. Nothing what could be done on Mageia side. See the link to the developers: https://github.com/dracutdevs/dracut/issues/924

Thanks for the feedback and the links.

On Bugzilla, Fedora is mentioned at the beginning. What does that have to do with Mageia? I can't put it together.

Because someone reported that using Fedora as Fedora got the dracut updates first. But dracut is used by basically all distros, so all are affected if there's no workaround applied.

Thank you for the explanation.

I would like to do the manual fix for mga#28528. I have read this, looked around again on the subject, but I cannot implement it. How do I proceed?

Step 1): Do I type in the console: "cat /etc/dracut.conf.d/51-mageia-resume.conf" and then check that the output does not contain "add_dracutmodules"?

Step 2): Do I type in the console: "echo 'add_dracutmodules+=" resume "' >> /etc/dracut.conf.d/51-mageia-resume.conf"

Step 3): Do I enter in the console?: dracut -fv

Thanks in advance

Yes.

Thank you for the feedback.

Step 1): I enter the command and don't understand the output I get and what to do with it:

Code: Select all

[luethypc@localhost ~]$ cat /etc/dracut.conf.d/51-mageia-resume.conf
add_device+=" UUID=0d550460-2c41-47ea-8015-5de61342c65e "

added code tags ~Germ

First step is satisfied. 51-mageia-resume.conf does not contain add_dracutmodules

That means dracut will add this device (which is usually your swap partition) to enable this during early boot in the initrd, this is required for resume in some configurations.

Here's the description from the man page of dracut.conf:

Code: Select all

       add_device+=" <device> "
           Bring up <device> in initramfs, <device> should be the device
           name. This can be useful in hostonly mode for resume support
           when your swap is on LVM an encrypted partition.

Thank you for the further information.
Now I was able to carry out the instructions from the manual fix and now the hibernation mode works. I am very happy, thank you for the support.
