My laptop is screen # 1 and has been selected as the main display.
However, on my screen 2 is all the desktop apps and so on… How can I change that the entire desktop content remains on my laptop (screen 1; checked for "Use this display as main display") and not always on mine when connected second screen wander.
Many Thanks.
Settings -> System -> Display
Select laptop display
scroll down
"Use this display as the main display"
