Systemd suspend doesn't go to deep sleep

Hi All,

I'm having trouble with suspending with systemd my desktop PC: AMD Ryzen 5 35003600 with Radeon 6700XT.

# cat /sys/power/mem_sleep
s2idle [deep]
# echo mem > /sys/power/state

works fine. System goes to deep sleep - fans turn off and I need to push power button to resume.

But when I try to use:

$ systemctl suspend

command or try using suspend option in Gnome (wayland), the screen goes black for a few seconds (fans on), then I'm greeted by lock screen.
I think it's probably something systemd related, because directly echoing into /sys/power/state works fine and system resumes correctly, but I can't tell what's wrong.

Here's my config:

$ cat /etc/systemd/sleep.conf
[Sleep]
AllowSuspend=yes
AllowHibernation=no
AllowSuspendThenHibernate=no
AllowHybridSleep=no
SuspendState=mem
MemorySleepMode=deep

and logs:

$ journalctl -b -g suspend
sep 15 22:11:07 desktop systemd-logind[635]: suspend requested from client PID 9489 ('systemctl') (unit user@1000.service)...
sep 15 22:11:07 desktop systemd-logind[635]: The system will suspend now!

Thanks for help

EDIT: fix typo in CPU name

It could be an issue related with your login display manager (lightdm, sddm, gdm...). Try disabling "lock screen after suspend" option on the power manager settings.

Re: Systemd suspend doesn't go to deep sleep

"journalctl -b -g suspend" won't tell anything here.
Please post your complete system journal for a boot covering the failed suspend

sudo journalctl -b | nc termbin.com 9999
