Sorry - that problem is in the release notes for 17.10, and is a
different problem/bug;

"
When an external monitor is connected to a laptop, the login screen is
only displayed on the internal one and in some case is not visible
(1723025)
"

I note also, there is

"
Systems may fail to boot when connected over DisplayPort to an
external screen, on NVidia graphics hardware such as the GTX970
chipset. (1723619)
"

I do not know what is DisplayPort (the HDMI output socket?), but I am
wondering whether that problem involves nouveau, and thence, systems
with nVidia Optimus.

Also, whilst this is now digressing from the thread topic, I am
wondering whether, when 18.04 is released, the Release Notes will
include changes from 16.04 to 18.04  (LTS to LTS), or, just changes
from 17.10 to 18.04, in addition to unresolved problems.
