the exact same is happening to me, also on a latitude e7470, but with
arch linux, 4.14.6 kernel.
I can also reproduce this behaviour including the not-in-reality-existing
monitor showing up in xrandr in Ubuntu 17.10 live ISO. Latest Fedora 28 live
also affected. As this problem doesn't go away with booting LTS kernels, I
suppose it's not a kernel related bug, nor related to video drivers.
I'm also not sure if this is really a duplicate of bug #1505409, as this is new
behavior and nothing a bug from 2015 could be. Ubuntu 16.04/10 not affected for
example.

Title:
Screen turn on/off 3 times and DP-1-3 connected but nothing is
connected [latitude e7470]
Status in xserver-xorg-video-intel package in Ubuntu:
Confirmed
Bug description:
Gnome-shell crash and restart after the login and the screen flicker 1
time (3 with wayland) in Ubuntu 17.10 with my DELL latitude e7470
laptop.
If I go in display settings I notice a second monitor Synaptics Inc
24'' which doesn't exist in reality. In Wayland after the screen stop
flickering I don't have any other problem and that monitor is not
present there.
xrandr | grep -i ' connected'
eDP-1 connected primary 1920x1080+0+0 (normal left inverted right x axis y
axis) 309mm x 174mm
DP-1-3 connected (normal left inverted right x axis y axis) <-- I don't have
anything connected to this port
With Fedora 26 I don't have this problem but I'm not yet able to find what
package is the culprit.
I believe this problem is related to Displayport 1.2, I don't have any dock
nor I need to connect more than 1 monitor and would be satisfied just having
one interface.
