 Posted: Wed Mar 05, 2025 10:44 pm Post subject: Hibernate does not work after update |
 |
|
[Administrator note: this post, and the first 2 responses, were originally attached to the topic Hibernate does not work after update. However, that topic dealt with nVidia drivers preventing hibernate, and this appears to deal with logind not issuing a valid hibernate command to the system. -Hu]
I am seeing the same effect for some time that
just locks the screen. As root the command | Code: | | echo disk > /sys/power/state |
works fine however. Nothing recorded on dmesg apart from "[ 123.116971] elogind-daemon[2727]: The system will hibernate now!". It used to work fine.
Running as root as no effect either, I have no NVIDIA card.
Any idea where else to look for hints? |

V-Li, all the other posts in this thread seem specific to the proprietary nVidia drivers. Since you are not using an nVidia card, I suspect you have a different problem. Shall I move your post to a new thread?
Regardless, it could be useful to know the last known good and first known bad logind versions for you. Since it does work for you using echo disk (which did not work for dabler), I think your problem is in logind, whereas the other affected users had a kernel-level problem. |

Downgrade is not possible, I assume it used to be 246.10-r3, but I actually cannot tell if it was a kernel upgrade or elogind. So I would love to check what is going on, but cannot find a log message.
A separate thread is fine by me. |

I have what looks like the same problem on a laptop with intel graphics. It was ok when I was away with it in late December, but hibernate did not work on a recent trip. The fail mode is that the screen goes black as if hibernate is doing something, then the lock screen appears almost immediately[/list].
Looking at history with "genlop -s", during the December trip (hibernate working) the laptop had:
- sys-auth/elogind-252.9-r2
- sys-kernel/gentoo-sources-6.6.62
- sys-libs/pam-1.6.1
And this last trip (hibernate not working):
- sys-auth/elogind-255.5-r2
- sys-kernel/gentoo-sources-6.6.74
- sys-libs/pam-1.6.1
I just tried reverting to sys-auth/elogind-252.9-r2 and hibernate now works from the KDE logout menu. |

V-Li you've provided so much information that it almost looks like you want to solve it on your own :)
Best Regards,

For me also stopped working after upgrading the kernel to linux-6.12.16-gentoo. When I switched back to kernel linux-6.6.74-gentoo it does work again, so the kernel upgrade is at least involved in the problem, if not the sole cause.
Edit: Someone reported a bug in elogind concerning Suspend to RAM which might be related. |

It gets more complicated: now I downgraded pam to 1.6.1 and elogind to 252.9-r2. With those in place, loginctl hibernate seems to work with kernel 6.12.16 running - at least the screen goes blank after the usual amount of time. But my system does not resume, but instead does a clean boot. Using kernel 6.6.74 everything works as expected.
When upgrading the kernel I didn't change any of the old kernel options, only added the new ones. |

When resuming, Linux kernel loads but then gets replaced by the copy in the hibernate image. That's why it needs to be pointed to the resume partition/file. How do you do that? For quite a long time CONFIG_PM_STD_PARTITION didn't work for me and I had to pass it on the kernel command line. I'm pretty sure it didn't work for a lot of the 5.x kernels. In fact I still have it in CONFIG_CMDLINE as well but I remember once I booted a kernel that didn't have it that resumed normally which prompted me that issue was resolved, at least for me.
I haven't tested if hibernation still works with 6.12.17 which I'm currently using, but I remember it worked with 6.13.

I do pass it on the command line, which used to work until the upgrade to kernel 6.12.16. As I wrote above, I didn't change anything regarding the kernel config. Grub command line for 6.12.16 still has the same resume parameter as for kernel 6.6.74. |

I tried with my kernel and hibernation worked. It's one version above yours - 6.12.17 but I suggest trying 6.13 as well, just in case it's something that's known and fixed there. In my case it was S3 sleep that was broken for nearly 2 years. Somebody on the forums reported it worked on 6.13 and later I found the fix was present in 6.12.17 as well. I wanted to be on the long term kernel so I switched to it.
