Finally these two command should display services as active

# systemctl status display-manager.service
# systemctl status displaylink.service

If all of these command are correct, your device should be correctly detected and usable.

;-)

[1] - The output of '# systemctl status display-manager.service' is fine::
● gdm.service - GNOME Display Manager

But,
[2] - The output of '# systemctl status displaylink.service' returns failure::
● displaylink.service - DisplayLink Manager Service
Loaded: loaded (/lib/systemd/system/displaylink.service; enabled)
Active: activating (auto-restart) (Result: exit-code) since Wed 2015-11-25 15:30:17 JST; 1s ago

Main PID: 2538 (code=exited, status=203/EXEC)

Even after I tried to activate the service with::
'# systemctl restart displaylink.service'

please, share any lights on how I may get around this issue.
