Public bug reported:
Using the night light on both the built-in screen and an external
monitor (connected via VGA) in "Join Displays" mode, everything works
fine until the screen goes to sleep (aka "blank screen" in "Settings >
Power > Power Saving): the night light is still active on the built-in
screen but not on the external monitor anymore. I have to unplug and
plug back in the VGA for the night light to be restored on the external
monitor. Turning the night light on and off does not restore it on the
external monitor.
I have checked other bug reports related to night light, but couldn't
find a description of my issue.
