Facing the same issue on HP Pavilion 15

4

The display recovers for a few seconds after waking it again from sleep, but then the issue occurs again if it isn’t plugged in

I have the same issue after upgrading today (Dec 22nd) to kernel 6.12.5. I have a Lenovo IdeaPad Gaming 3 15ARH05 with hybrid graphics (AMD/NVIDIA) runing Fedora Linux 41 Workstation (GNOME). The system is up to date as of writing this. Please fix ASAP!

There definitely have been some significant regressions in 6.12.5. It’s probably recommended to revert to 6.12.4 for the time being or install 6.12.6 from updates-testing.

You can use dnf versionlock to prevent new versions of the kernel packages from being installed if you choose to rollback until 6.12.6 is considered stable.

same issue. Dell Latitude 5515 (AMD Ryzen 7 series)

only started occuring on 6.12.5-200

laptops fine on reboot (unplugged) until i either close the lid or it goes into suspend. Once active again, screen flickers slowly for a second, then rapidly, then screen goes black until forced reboot.

8

same here, it works fine when you start laptop without being plugged in then plug in

9

I have the exact same setup just a different model, same issue, seems to be related to iGPU or something with brightness

Hi.
I am facing the same issue with a Lenovo X13 Gen2, as described in Kernel 6.12.5 - display brightness issue at resume.
I reverted kernel to 6.12.4.

12

There’s a workaround for meantime, setting power profile to performance fixes it but once you go back to balanced or power saver, it will return

Still happening after updating to 6.12.6 :confused:

14

Yes, the issue is still there with 6.12.6, unfortunately, and we are running out of kernels… next update if the issue is not fixed we can’t go back to a working kernel and I will have to jump ship and install a different distro…

15

I am sorry I have to say this, but this is a major f**k*p from the Fedora kernel team. Fedora is one of the major distros out there and I never had an issue in 5 years since using it.

Hi,

I went ahead and installed that - kwizart/kernel-longterm-6.6 Copr while they are working on issues with kernels 6.8, 6.9, 6.10, 6.11 and now 6.12. Works for me, hopefully it will for you as well.

what’s more irritating is that theyre not even looking at the bugzila report

18

… for me it’s not irritating but to be expected…

19

there are even enough logs to see where this happened and not…

20

Yes it’s a bit of a bug, but please take into consideration it’s peak holiday season and most of the maintainers are with family and celebrating.

A bit of patience goes a long way and they’ll fix it soon, that I am certain of.
