--- Comment #6 from Maxim Malkov <wgh at torlan.ru> ---
I also encountered this bug on ThinkPad T440. In fact, I think this's a
regression: I never seen this bug on 4.14. It only appeared when I upgraded to
4.16, and it didn't go away after I upgraded to 4.17.

The most prominent side effect is that systemd-logind fails to suspend on lid
close, believing that there's external screen attached.

Interestingly, although `grep . /sys/class/drm/*/status` will say that monitor
is connected, on my machine, simply running `xrandr` will unstuck the status
(and the grep command will now correctly report "disconnected" as well).
