PC failing to sleep properly | Arch Linux Community | Page 1

I am running an Arch based system (EndeavourOS) with KDE plasma as my DE, and I am running into an issue that when I tell my PC to sleep, the screens go black yet the PC is still lit up and sounds like it's still running? Pressing mouse or keyboard inputs doesn't wake the system up, the PC still chugs like it's under light load but won't turn the screens back on

I have to force shutdown after sleep, and upon rebooting. This began after a regular system update through yay yesterday, and unfortunately I didn't remember to install Timeshift after reinstalling the operating system some months ago so I have no backup of the working version

#

My PC passed memtest86+ without error, and logs include these errors:
kernel asus_wmi: failed to register LPS0 sleep handler in asus-wmi

i have the same issue honestly. but mine is asus spd5118 ddr5 temp module.

#

first of all

#

do u have secure boot on?

slender hedge Aug 25, 2025, 11:37 PM

#

No

craggy pagoda Aug 25, 2025, 11:38 PM

#

your sysrem probably blocked sleeping because theres a kernel taint.

#

i had same issue in ubuntu.

#

This is the journal log if I grep suspend

#

Wdym by kernel taint?

#

do u have a nvidia graphics card

slender hedge Aug 25, 2025, 11:40 PM

#

No, I run AMD. It's a 6950 xt

craggy pagoda Aug 25, 2025, 11:40 PM

#

sudo journalctl -b | grep -i suspend
sudo dmesg | grep -i acpi

#

u can write this, to enable deep sleep. cat /sys/power/mem_sleep
echo deep | sudo tee /sys/power/mem_sleep

#

for sanity check, i will also want this. cat /proc/sys/kernel/tainted

#

The first journalctl command returns nothing

#

cat /proc/sys/kernel/tainted returns 12801

#

What will change if I enable deep sleep?

craggy pagoda Aug 25, 2025, 11:46 PM

#

#

can u do this, to check propritiary drivers

#

if they re tainting

#

okay. lsmod | grep -vE "snd|hid|i2c|amdgpu|drm|kvm"

#

now the drm stuff if they are loaded

slender hedge Aug 25, 2025, 11:47 PM

#

I am on linux-zen if it helps anything

craggy pagoda Aug 25, 2025, 11:48 PM

#

zen?

slender hedge Aug 25, 2025, 11:49 PM

#

The zen kernel

craggy pagoda Aug 25, 2025, 11:49 PM

#

#

#

it uses own flags and stuff.

#

from here, theres not much like tainting driver

#

they are stable

slender hedge Aug 25, 2025, 11:51 PM

#

Switching back to the arch kernel could be the fix?

craggy pagoda Aug 25, 2025, 11:52 PM

#

can u edit the /etc/default/grub linux dafault line as such: quiet splash mem_sleep_default=deep acpi_osi= amdgpu.aspm=1

#

then this sudo grub-mkconfig -o /boot/grub/grub.cfg

#

we will try manual commands if this doesnt work

#

then sudo reboot

slender hedge Aug 25, 2025, 11:56 PM

#

is there somewhere I should be looking specifically to paste that in or overwrite another option with?

#

oh wait duh

craggy pagoda Aug 25, 2025, 11:56 PM

#

write sudo nano /etc/default/grub

#

theres GRUB_CMDLINE_LINUX_DEFAULT line.

slender hedge Aug 25, 2025, 11:58 PM

#

just add the command to the rest of the things in that option then?

craggy pagoda Aug 25, 2025, 11:58 PM

#

slender hedge just add the command to the rest of the things in that option then?

no.

#

select whats in there. " .... "

craggy pagoda Aug 25, 2025, 11:59 PM

#

craggy pagoda can u edit the /etc/default/grub linux dafault line as such: quiet splash mem_sl...

copy whats after the two dots, overwriting whats on there. not near them.

#

"quiet splash" (prolly what it is right now) "quiet splash mem_sleep_default=deep acpi_osi= amdgpu.aspm=1"

#

then control O to save

#

control X to exit

#

systemctl reboot

#

then leave a journalctl -f running, open another terminal and write systemctl suspend

slender hedge Aug 26, 2025, 12:02 AM

#

craggy pagoda then this sudo grub-mkconfig -o /boot/grub/grub.cfg

do this before rebooting?

craggy pagoda Aug 26, 2025, 12:02 AM

#

slender hedge do this before rebooting?

yes

#

else it wont be saved

#

to linux command line

slender hedge Aug 26, 2025, 12:04 AM

#

I did it and now my PC won't get past the grub loader

craggy pagoda Aug 26, 2025, 12:05 AM

#

hm?

#

what do u mean

#

did u not let it complete the build?

craggy pagoda Aug 26, 2025, 12:05 AM

#

craggy pagoda then this sudo grub-mkconfig -o /boot/grub/grub.cfg

this is VERY important

slender hedge Aug 26, 2025, 12:06 AM

#

I did the command ended and then I rebooted

craggy pagoda Aug 26, 2025, 12:06 AM

craggy pagoda Aug 26, 2025, 12:10 AM

#

slender hedge Aug 26, 2025, 12:10 AM

Okay I've pressed e

#

craggy pagoda Aug 26, 2025, 12:11 AM

#

#

just second im reading a forum for being sure

slender hedge Aug 26, 2025, 12:13 AM

#

I think I'm just gonna go replace the grub file with the backup copy I saved, unless this is salvageable from here?

#

I have a live USB available to me

craggy pagoda Aug 26, 2025, 12:16 AM

#

can u write nomodeset to the end of the line linux

#

delete what we wrote

#

so it will be, deleting till splash, and writing nomodeset.

#

nomodeset will disable graphics card drivers and dkms.

#

so your pc will boot right up.

slender hedge Aug 26, 2025, 12:19 AM

#

Okay it booted

craggy pagoda Aug 26, 2025, 12:20 AM

#

good

#

can u show me where u re right now?

slender hedge Aug 26, 2025, 12:20 AM

#

Homescreen

craggy pagoda Aug 26, 2025, 12:21 AM

#

can u write this to rerminal to test something. its forced suspend. if this is true. we will change security. sudo sh -c 'echo deep > /sys/power/mem_sleep'
sudo sh -c 'echo devices > /sys/power/pm_test'
sudo systemctl suspend

#

if the system sleeps and boots right back up but u didnt touch nothing

#

its security related

slender hedge Aug 26, 2025, 12:25 AM

#

Okay so it "suspended", my screen went dark but my PC is still active. Pushing a keyboard button woke up the PC again tho

craggy pagoda Aug 26, 2025, 12:26 AM

I dunno, I loaded the regular arch kennel though just now after setting things back up, but the sleep function still isn't behaving properly

craggy pagoda Aug 26, 2025, 12:44 AM

#
