[SOLVED] Various systemd services being stopped

Hi!
I noticed that occasionally systemd-logind just kicks me back to the login screen on the console.
(I'm using startx, though sometimes this issue occurs even if Xorg isn't running.)
Xorg.0.log has a line about

 [  1879.799] (EE) 
Fatal server error:
[  1879.799] (EE) systemd-logind disappeared (stopped/restarted?)

(full log: ix.io/3oSt )

Which led me to check

 #journalctl -u systemd-logind 

Here's the log from the last time it happened:

-- Boot 2601d03885e14662adc7c02f3e10b87e --

Jun 05 13:07:15 dream systemd-logind[2412]: New session 3 of user faefeyfa.

(full log: ix.io/3oSp)
But there doesn't seem to be anything telling me why it's doing this. In a few previous boots systemd-logind was recorded as going into "scheduled restarts", so I went into /usr/lib/systemd/system/systemd-logind.service and changed

 Restart=no 

which removed the message about "scheduled restarts" in the logs, but did not actually fix the issue.

I think this started happening after a kernel/systemd update, but I've tried downgrading both and nothing happened. (I'll try again sometime later, this time with older versions, and see if I can get better results.) The other think I remember changing is changing my logind.conf to hibernate on lid switch instead of suspend, which I suppose could have broken something, but I don't know where to start debugging.

So now I have no idea what to do. Please send help.

Thanks!

Re: [SOLVED] Various systemd services being stopped

Xorg is apparently correct, systemd-logind was started again. The absence of any messages prior to the launch looks to me like something SIGKILLed systemd-logind. I'd imagine a restart being indicated with at least Stopping systemd-logind in the logs which is not there around this time. So that's probably why Restart=no did not work.
I also imagine crashes being noticed by Systemd and also noted in the logs. Or maybe not?

I don't see suspend/hibernate config being at fault, as the log output prior to the mysterious restart hints at those events being handled as they should. Still, you could post the logind.conf. Maybe pressing some button configured there makes systemd-logind crash unnoticed?

Which does note that systemd-logind is stopping.
Also, here's a full log of a boot where I log in and wait until everything restarts: http://ix.io/3pfl
It seems like it's not just systemd-logind being stopped, but a bunch of (possibly all?) systemd services.

Re: [SOLVED] Various systemd services being stopped

Try not using dhcpcd as dhcp client for NM, use dhclient or the built-in instead.
