That's saying that gdm was started but died, so you must have another
display manager running that was NOT started by systemctl/systemd. The
only way to find that is to, as root, "ps ax | grep dm", look at that
process list and figure out which display manager is running. Odds are
that it'll have the word "session" somewhere in its command line, too.
Won't swear to it.
On your F27 machine, are you certain that boots up in GUI mode? Or
do you start X by using "startx" or something equivalent. On a couple of
VMs running XFCE:
[root@nginxingest ~]# cat /etc/redhat-release;systemctl status
display-manager
Fedora release 26 (Twenty Six)
● lightdm.service - Light Display Manager
Loaded: loaded (/usr/lib/systemd/system/lightdm.service; enabled;
vendor preset: disabled)
Active: active (running) since Thu 2018-10-04 17:44:07 GMT; 2min 31s
ago
[root@localhost ~]# cat /etc/redhat-release;systemctl status
display-manager
Fedora release 27 (Twenty Seven)
● lightdm.service - Light Display Manager
Loaded: loaded (/usr/lib/systemd/system/lightdm.service; enabled;
vendor preset: disabled)
Active: active (running) since Thu 2018-10-04 10:44:57 PDT; 3min 43s
ago
Note that both of those boot up into GUI mode. I do NOT run "startx" to
bring up X on them.

Uh, it should be "systemctl status lightdm" (typo in your command?). If
you get a "not found" error, it's because that display manager isn't
installed. From my F26 system:
[root@nginxingest ~]# systemctl status lightdm
● lightdm.service - Light Display Manager
Loaded: loaded (/usr/lib/systemd/system/lightdm.service; enabled;
vendor preset: disabled)
Active: active (running) since Thu 2018-10-04 17:44:07 GMT; 6min ago
[root@nginxingest ~]# systemctl status gdm
Unit gdm.service could not be found.
And that's because gdm is NOT installed on that machine.
