My laptop (GeForce GTX 860M) display goes black at random time=
s, while the
external display (if plugged in) remains visible. The blanking is not limit=
ed
to contexts when the external display is plugged in. When on battery, or
plugged in, in all those contexts the laptop display very predictably goes
black after short use of the display. The only context when it remained vis=
ible
is when there is no application launched on the laptop display, just the
desktop picture visible.

I have described a lot of detail in this Ask Ubuntu post:
https://askubuntu.c=
om/questions/1024576/laptop-screen-randomly-switches-off-ubuntu-16-04-4-lts=
-external-display-attach

Today I have switched to the NVIDIA binary driver and it appears that no
blanking occours anymore. At least in the typical scenarios that used to ca=
use
the blanking, for example full-screen YouTube video.

My guess is that the built-in display mode "brightness turned a bit do=
wn" that
kicks in in some power-saving scenarios, is not properly implemented and ca=
uses
the display go black.
