#linux #troubleshooting There seem to be a regression in the last kernel update in #Fedora 38. Going from 3.6.11 to 3.6.12, screen will not wake up coming back from hibernation. Had to revert to 3.6.11, which seems to work for me with an external Dell UltraSharp 34.

@oatmeal I presume you meant 6.3.11 to 6.3.12?Anyway, there were many of us with AMD cpu/igpu systems that 6.3.11 booted to a hanging system. I think 6.3.12 was a "quick remediation" of that while keeping the security fix for a recent critical CVE. I think that you should consider submitting a bug report on this.In the meantime, can you still boot from 6,3.8?Good luck!

@jrredho thanks. Corrected. It’s an AMD slimbook one. I’m able to boot into 6.3.11 and all the F38 kernel worked flawlessly thus far in fact.

@oatmeal Also, do you mean sleep and not hibernation?If it's sleep, then yeah, this is one of the most fragile aspects I've found about running #fedora. It comes and it goes kernel update to kernel update for me. This is an artifact of #fedora's approach to pushing kernel updates fairly often..Lately, though, it has mostly worked just fine. It is definitely not robust.You don't happen to have any sort of BIOS setting that reflects sleep state options, do you?

@jrredho I think… my default is set to hibernate. How do I verify this?

@oatmeal It is pretty unlikely it's hibernating, which means it writes a copy of your computer states to disk and shuts down.You are probably talking about "suspend", which is also called sleep. which doesn't shutdown your computer. You'll likely see a blinking light on your power button, and this will be shown in your system journal if you do a suspend and wake up cycle on a kernel that works for you.For the latter, after waking:sudo journalctl -b 0

@jrredho I didn’t really look. I figured it was the kernel because it started happening right after an upgrade. Yes it’s sleep not hibernate, my bad. Is there any bios setting I can change to help with this happening g again?

@oatmeal Maybe. Try booting into the BIOS and look around for something to do with sleep or suspend. Thinkpads have an option to suspend to S3 vs S0, I believe, which is denoted in the BIOS as a Suspend menu option list of "Windows" or "LInux". If you can pick Linux, look in your journal after booting for a line like this one:kernel: ACPI: PM: (supports S0 S4 S5)If your system supports power state S3, I believe, it'll likely be more robust about suspend-wake'ing.Good luck!

@oatmeal Oh, and even if you can't change this setting in your BIOS, it's not the end of the world. You just have to boot a previous kernel version that works, and wait for another update to roll down. You can use grubby to select a given kernel by default other than the most current.I set my system to keep a total of 4 kernel boot option instead of 3 just to account for any time delays.This is a cost of doing business with a distribution that is pretty cutting edge. It's a small one, imo.

@jrredho thanks for the tip about grubby. Well, this is why I chose Fedora, because it's bleeding edge :)
