[SOLVED] GDM does not start automatically

I can start gdm just fine with "systemctl start". However, after "systemctl enable gdm.service", gdm does not start at boot:

$ systemctl status gdm.service
● gdm.service - GNOME Display Manager
   Loaded: loaded (/usr/lib/systemd/system/gdm.service; enabled)
   Active: inactive (dead)

Error messages in /var/log/messages.log:

P.S. Could this be related to dhcpcd's long start time?

         13.072s dhcpcd@eth0.service
          8.465s psd.service
          3.541s lm_sensors.service
          3.116s alsa-restore.service
          3.116s gpm.service

Edit: The solution was to do

# rm /etc/systemd/system/default.target

It's even explained in the Wiki at https://wiki.archlinux.org/index.php/display_manager. Just not in the GDM article which I had looked at for help. :-)
