[systemd] suspend.target fails (preventing suspend)

Hello !

Recently, my laptop didn't go to sleep when I closed the lid, and only locks the screen. It used ot work flawlessly though.

Eventually, systemctl suspend failed. Here are my journalctl logs:

Feb 27 15:43:42 laptop kernel: PM: Preparing system for freeze sleep
Feb 27 15:43:47 laptop systemd[1]: systemd-suspend.service: main process exited, code=exited, status=1/FAILURE
Feb 27 15:43:47 laptop systemd[1]: Failed to start Suspend.
-- Subject: Unit systemd-suspend.service has failed

-- 
-- The result is failed.

Feb 27 15:43:47 laptop systemd[1]: Unit systemd-suspend.service entered failed state.
Feb 27 15:43:47 laptop systemd[1]: systemd-suspend.service failed.

However, I haven't changed my /usr/lib/systemd/system/suspend.target whatsoever. But here is its content:

[Unit]
Description=Suspend
Documentation=man:systemd.special(7)
DefaultDependencies=no
BindsTo=systemd-suspend.service
After=systemd-suspend.service

And here is the content of /usr/lib/systemd/system/systemd-suspend.service:

[Unit]
Description=Suspend
Documentation=man:systemd-suspend.service(8)
DefaultDependencies=no
Requires=sleep.target
After=sleep.target

[Service]
Type=oneshot
ExecStart=/usr/lib/systemd/systemd-sleep suspend

It really seems to be coming from sleep.target:

# systemctl list-dependencies systemd-suspend.service                        
systemd-suspend.service
● ├─system.slice
● └─sleep.target (this one is red)

/usr/lib/systemd/system/sleep.target:

[Unit]
Description=Sleep
Documentation=man:systemd.special(7)
DefaultDependencies=no
RefuseManualStart=yes
StopWhenUnneeded=yes

What am I missing here?

Anyone got any idea of what's going on with sleep.target?

Could try systemctl status systemd-suspend.service

Here is the output of `systemctl status systemd-suspend.service`:

Re: [systemd] suspend.target fails (preventing suspend)

I can confirm that the file contents that you posted are the same as mine, and thinking about it, when I close my laptop lid it doesn't suspend either; I have to press the sleep button that has a picture of a moon on it (in my case Fn+Esc).  I suppose you could try pressing a sleep button if you have one to give you more information.  I've just noticed that in /etc/systemd/logind.conf I have HandleLidSwitch=ignore .

Re: [systemd] suspend.target fails (preventing suspend)

I haven't changed the default values of logind.conf, so HandleLidSwitch is set to "suspend" by default.
Also, I haven't got any sleep key unfortunately.

Anyways, `systemctl suspend` should work nevertheless, which is not the case.
