[SOLVED] systemd display-manager.service problem

Hi!
After the upgrade of systemd, i noticed today this error in dmesg:

systemd[1]: Cannot add dependency job for unit display-manager.service, ignoring: Unit display-manager.service failed to load: No such file or directory. See system logs and 'systemctl status display-manager.service' for details.
systemctl status display-manager.service
display-manager.service
	  Loaded: error (Reason: No such file or directory)
	  Active: inactive (dead)

The strange thing is why systemd tries to load a service that doesn't exist! And what is this unit for? I'm using slim to load my xfce desktop, and everything works well...
Any idea?
Thanks!
EDIT: Uhm, may be the alias in slim.service, set to display-manager.service, is the problem? Or may be this is not a problem, but it is its normal behaviour , and i misunderstood something! Is it?

There has been a change regarding display managers. up until now they were WantedBy graphical.target, which was kind of stupid because this allowed you to enable multiple display managers.
Instead graphical.target now Wants display-manager.service and all display managers are supposed to install the appropriate Alias. Afaik all display manager service files have been updated ragarding this and a "systemctl reenable slim.service" should fix it.

Didn't work for me.  I use LXDM, and i tried systemctl reenable lxdm.service.

seems like lxdm hasn't been updated yet.
It was fixed in git but the new version hasn't been released yet: https://projects.archlinux.org/svntogit … cc2afee8b9

just wait for the lxdm update and then try again. As far as I can see the error message can be safely ignored until then.

Re: [SOLVED] systemd display-manager.service problem

Can I simply ignore that error if I am not using any graphical login manager?
