I've found that I can make the system stable with the following
settings:
System Settings:
Privacy>Screen Lock: On
Power>Dim screen when inactive: Off
Power>Blank screen: 10m
Power>Automatic suspend:
On Battery Power: On
Delay: 20m
Plugged In: On
Delay: 1h
Power>When the Power Button is pressed: Suspend
Devices>Displays>Night Light Off
Gnome Tweaks (installed):
Power>Suspend when laptop lid is closed: On
Upgraded BIOS.
Graphics are:
Intel® Sandybridge Mobile
NVidia Optimus
It seems to hang with "Night Light" and "Dim screen when inactive"
enabled. So, I have those off. I originally had "Night Light" enabled
with sunrise and sunset. That caused my system to try to hang around
sunrise and sunset. And it generally would hang when unsuspending after
one of those options activated.
Anyhow, I will be trying this out sometime soon to prevent that sort of
trouble:

I expect that will allow me to use the "Night Light" and "Dim screen
when inactive" options.

Bug description:
Dell XPS 13 9350 on AC power left running overnight, suspends after a
given timeout. When coming back the next morning sometimes the laptop
resumes to an aubergine desktop (just the screen, no GDM) and cursor
and sits there forever. Sometimes it resumes to a black screen and
cursor.
