Solved *** Linux Mint 21 hibernate

[nekrub2]

Under LM 20.3 Cinnamon I added a launcher on desktop doing

pkexec env DISPLAY=$DISPLAY XAUTHORITY=$XAUTHORITY pm-hibernate

It prompted my password and wrote everything to the swap partition and afterwards shut down.

Unter LM 21 the password prompt is there, but afterwards it just shut down. Clicking on the start button it starts into the login window and all the open applications are closed.

Is there anything I have to modify for LM 21?

I was glancing at some of the new entries in dconf editor this morning to see what was new. I recall under one of the headings, probably under cinnamon or perhaps under muffin, that you could choose between shut down and hibernate.

Also some other things there that are helpful such as whether or not to open new windows full screen.

How big is your swap?

[nekrub2]

13 GB. Definitely enough as I have only 4GB RAM.

[Cosmo.]

Is this a swap file or a swap partition?

Are the packages hibernate and uswsusp installed? Otherwise do it.

[nekrub2]

it is a swap partition. Cannot find hibernate and uswsusp in the software manager. Where can I find them?
Thanks a lot

I just did a check and you are right, both packages do no longer exist in the repositories.

I have here only a LM 21 test system, but I will in the next months not upgrade to it. So I did not deal with such questions and this will hardly happen in this year. Following that I must retreat here.

[nekrub2]

Thanks anyway. Maybe I was a bit fast in upgrading and had to pay the price for it now.

By using Timeshift you can revert.

Nekrub2, I can not speak to your use of pm-hibernate, but I can confirm the "[GUIDE] How to hibernate to a swap file in Linux Mint 19.x" posted by gm10 as viewtopic.php?f=42&t=284100 currently works in Mint 21. It requires use of a swap FILE, not swap partition, but that should not be significant. You initiate hibernation either though the Mint menu (power off), or by

Code: Select all

systemctl hibernate

for which you can easily create a launcher.

Works great for me as well using Linux Mint 21.

systemctrl hibernate says it failed because of rights and meanwhile a password window pops up. After the password entry the machine shuts down but I do not see it writing into the swap file. After starting the machine it comes to the login screen and on the desktop all apps are closed like a normal shutdown but on like hibernate. In this way I could do a normal shut down.

systemctrl hibernate says it failed

If so, then you did not build the structure AS DESCRIBED IN THE REFERENCED THREAD. Did you delete your swap partition and create only a swap file? Did you run the "can hibernate" test and get a "yes" answer? I can not debug the process for you because I did not write it. I can only report my experience. I suggest you report your issues in the referenced thread. Maybe the author can help you.

[nekrub2]

I did not delete the swap partition as I still think an own partition for swap is better than a swap file. Furthermore I do not want to fiddle around in the grub script as I have a dual boot with Windows and have more than once to do a grub repair.
So for me the subject is closed and I will mark it as solved.
