Sleep/Hibernation Issues

Greetings everyone,

Kernel: Liux 6.18.6-zen1-1-zen
DE: KDE Plasma 6.5.5
WM: KWin (Wayland)
CPU: 12th Gen Intel(R) Core(TM) i7-12700KF (20) @ 5.00 GHz
GPU: NVIDIA GeForce RTX (using nvidia-open-dkms)
Motherboard: TUF GAMING Z690-PLUS WIFI D4
Memory: 64GB DDR4 3600mhz

Not sure what other info might be helpful; but if I can provide more if needed!

So, I have been running arch for about 3/4 years now, and since day one I have had issues with sleep/suspension (hibernation too I think?)

What happens when I select "sleep" from the KDE start menu, my pc begins to sleep, then shuts down, immediately.

I have read through numerous resources including but not limited to:
https://wiki.archlinux.org/title/NVIDIA … er_suspend
And browsed a few more topics too in hopes to solve this.

Does anyone have any advice?

Re: Sleep/Hibernation Issues

cat /sys/power/mem_sleep

which suspend mode are you using?
also can you post journal logs?

journalctl -b -1| curl -F file=@- 0x0.st

Re: Sleep/Hibernation Issues

Output of first command:

s2idle [deep]

Text file generated by second command:

Thank you for your help!

Re: Sleep/Hibernation Issues

try removing "nomodeset", as it conflicts with "nvidia-drm.modeset=1" and can further interfere with suspend.

Re: Sleep/Hibernation Issues

I did remove nomodeset and rebuilt grub and to be safe rebuilt mkinitcpio as well.
Still seems to be shutting down upon triggering sleep.

Re: Sleep/Hibernation Issues

so it's still loosing memory, in

/etc/modprobe.d/nvidia-power-management.conf

add
"options nvidia NVreg_PreserveVideoMemoryAllocations=1 NVreg_TemporaryFilePath=/var/tmp"
then rebuild mkinitcpio
also

systemctl status nvidia-suspend.service
systemctl status nvidia-hibernate.service
systemctl status nvidia-resume.service

they are active right?

Re: Sleep/Hibernation Issues

I jsut created that modprobe.d config you mentioned and added the lines, then rebuilt mkinitcpio.

Restarted.

Then checked to see if nvidia-suspend.service nvidia-hibernate.service and nvidia-resume.service were enabled, they were. However, prior to creating that config and rebooting; they were disabled.

I did test sleep again, and it shut right down, again.

Again, I appreciate your help!

Re: Sleep/Hibernation Issues

uhm, one thing to ask does your BIOS has any options called "ErP Ready" smtg like that? some say when enabled it cuts power down to PCIe slots and USB to save power during sleep not sure if that's the cause, if there try disable and see....
to my understandings your logs showed an error about HPET being dysfunctional in PC10. in BIOS is there any options like "CPU C-States" make sure they are in Auto, also but check if there is an option for "Package C-State Limit." Setting this to C8 instead of C10 might/can stop the instant-shutdown in edge cases, again it's not proved just a hypothesis.

Re: Sleep/Hibernation Issues

ErP Ready is set to Disabled

CPU C-states is set to "Auto"

It did not look like there was any Package C-State Limit options that I could see.
I did see that both C8 and C10 are both supported according to my BIOS.

I can see if there is any form of update to my BIOS, but I don't have a windows partition to use ASUS's tools to update, so I may have to look into an alternative way to get that updated.

Re: Sleep/Hibernation Issues

does "s2idle" works/helps?
i think [deep] is the problem but never seen shuting down just because of it

edit:
s2idle might cause other issues not sure if it would help or may still shutdown just a test/hypothesis.

Re: Sleep/Hibernation Issues

I am unfamiliar with how to change to s2idle instead of sdidle [deep].

I was trying to look into it, but did not find the documentation for it (likely a skill issue here... haha)

Re: Sleep/Hibernation Issues

echo s2idle | sudo tee /sys/power/mem_sleep

cat /sys/power/mem_sleep

systemctl suspend

if it not shutdown probably your fans keep spinning....

If s2idle also results in immediate power-off, then yeah BIOS update might/should fix the problem....

Re: Sleep/Hibernation Issues

I am currently updating the BIOS via Asus EZFlash from within my BIOS.
I will report back if this works!

Again, I really appreciate your help!

Re: Sleep/Hibernation Issues

I have updated the BIOS. Which is wild how out of date it was. The last BIOS update my machine got was in 2022. Which tracks, which is when I last had Windows.
After updating the BIOS, I still have yet to get sleep/suspension working.

While I would like to solve this; if I can't it isn't a deal breaker.

Thanks again for the help. Maybe someone else will also have some things I can check, or help figure out what might be causing this.

Re: Sleep/Hibernation Issues

Actually I should be thanking you for your time and consistency , and due from 2022!?
atleast yours could update, im still waiting for mine with "fwupdmgr" on my HP

anyways, i still sus the board isn't handling PC10 state well, try limiting CPU idle states

intel_idle.max_cstate=4

(or =1 if 4 doesn’t change behavior).
if limiting C-states prevents the shutdown, it confirms a firmware/ACPI issue rather than linux configs

does the behavior change on a different kernels like LTS or hardened or mainline?, or does it power off identically there as well?  just wanted to know this is not becasue of zen
if none of this changes the outcome, then I have ntg left to add up....

Re: Sleep/Hibernation Issues

I tried adding both:

intel_idle.max_cstate=4

PC still shut down completely

intel_idle.max_cstate=1

PC still shut down completely

I am starting to wonder if there is something faulty about my PC. The other reason I suspect that is because when I press the power button to turn it on, it flickers on, and I have to hit the button a few times.

But I am unsure of what to do to troubleshoot that either.

Re: Sleep/Hibernation Issues

aww man, you could have told that earlier, a hardware issue lol, but anyways thanks, we both norrowed it down and also I don't have hardware knowledge much in this case, guesses are PSU or cables or your board
take to a authorized service centere....

also since "intel_idle.max_cstate=4" or "1" not helped, you can remove it.....

Re: Sleep/Hibernation Issues

Already removed
Again, thank you for help troubleshooting. Good news is that I was able to remove nomodeset, and potentially am avoiding other issues I may have.

Re: Sleep/Hibernation Issues

one last advice/practical note (take it or leave it): some vendors’ service centers are much more cooperative when a Windows install is present, since their diagnostics and firmware validation are built around it. Having Windows on a second drive or dual-boot can make the support process smoother if you end up going that route.
that said, the power-button flicker and hard power-off behavior would still be hardware-related regardless of OS. Hopefully support can pinpoint it quickly.

good luck with the rest.

Re: Sleep/Hibernation Issues

Thank you so much!
I likely will take apart my PC, and reassemble at some point. Make sure everything is connected securely. If that doesn't fix it; I may just opt to start getting parts for a new build)
