When you disconnect the external display, how exactly do you "disconnect"? What
brand and model is the external display? Disconnecting by powering down the
external display is not guaranteed to suffice with some models, such as one of
my Dells (21:9 U2913WM). Please try disconnecting the video cable from the
laptop if that is not what you have been doing.
"The wise are known for their understanding, and pleasant
words are persuasive." Proverbs 16:21 (New Living Translation)
