Public bug reported:
In a gnome session, my screen locks & turns off after a certain amount
of inactivity (but the system is not in suspend).
When I wake the display back up by moving mouse / hitting a key, it
seems like my external monitor is redetected -- both internal & external
screen blink black as if I had just plugged in my external monitor, and
then _sometimes_ the external monitor stays black (but thinks it is
receiving input). Other times it's fine, but when the issue happens,
the displays control panel still thinks the external screen is
connected, just nothing is visible. Unplugging & replugging the screen
fixes the issue, and it happens maybe 1/2 the time the display locks.
