[SOLVED] Suspend turns off monitor, but the system keeps running

IT'S SOLVED

Solution 1 :
Use X instead of Wayland.
(https://wiki.archlinux.org/title/GDM#Use_Xorg_backend)
(https://wiki.archlinux.org/title/GNOME#Xorg_sessions)

Solution 2 (w/ Wayland) :
If you find logs like this

$ journalctl -b
Freezing user space processes failed after 20.007 seconds (1 tasks refusing to freeze, wq_busy=0):
task:gnome-shell     state:R  running task     stack:0     pid:1239  tgid:1239  ppid:1146   task_flags:0x400000 flags:0x00004006

------------------------------------------------------------------------------------

RTX 4060 / GNOME Wayland

the monitor turns off, but the desktop keeps running.
even when I try to wake up, monitor stays black.

$ journalctl -b -1 --since "11:28"

OUTPUT: https://0x0.st/8vDj.txt

[Timeline]
11:28 Attempted to suspend the system. (monitor turns off, but the desktop remains active. Num Lock lights on)
11:31 Tried to wake up using mouse and keyboard.
11:32 Switched to TTY3 and pressed Ctrl+Alt+Del (system doesn’t reboot unless switched to TTY3)

This issue doesn't happen every time. Sometimes suspend works just fine.
So I really have no idea what's causing it.

Re: [SOLVED] Suspend turns off monitor, but the system keeps running

gnome-shell  gets stuck in the nvidia kernel module, please post your complete system journal for the boot:

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

to illustrate the overall configuration, but speculatively: https://wiki.archlinux.org/title/NVIDIA … P_firmware

nomodeset

Don't. Instead set

nvidia_drm.modeset=1 nvidia.NVreg_EnableGpuFirmware=0

Re: [SOLVED] Suspend turns off monitor, but the system keeps running

Do you get the same with an X11 gnome session (and *also* https://wiki.archlinux.org/title/GDM#Use_Xorg_backend )?

When I resume, I get a black screen with mouse cursor for a few seconds.
suspend works well. but something isn't smooth.

I think main issue is solved anyway
Thanks for your help

What does that mean?
gnome-shell no longre hangs up in

May 21 14:33:47 archlinux kernel: task:gnome-shell     state:R  running task     stack:0     pid:1225  tgid:1225  ppid:1132   task_flags:0x400000 flags:0x00004006

?

You could try to revert

May 21 14:33:26 archlinux systemd-sleep[1898]: User sessions remain unfrozen on explicit request ($SYSTEMD_SLEEP_FREEZE_USER_SESSIONS=0).

by moving away
/usr/lib/systemd/system/systemd-hibernate.service.d/10-nvidia-no-freeze-session.conf
/usr/lib/systemd/system/systemd-homed.service.d/10-nvidia-no-freeze-session.conf
/usr/lib/systemd/system/systemd-hybrid-sleep.service.d/10-nvidia-no-freeze-session.conf
/usr/lib/systemd/system/systemd-suspend-then-hibernate.service.d/10-nvidia-no-freeze-session.conf

Suspend works fine. But, there was a temporary black screen issue after resume.
I think it's probably my fault.
