Whenever I use an external monitor ( Dell HD, same as in-built ) I get this annoying screen selection popup which I cannot make go away. Is there any particular process I can " Stop / Kill " to make this popup from flashing all the time ? I am using 20.04

You should report it as a bug on your window manager project page, along with your dmesg
output.(Assuming it's not your cable that's broken and constant reconnections triggering this... in that case, get a new cable!)
You can also try this How do I enable and disable GNOME extensions from the command line?
If you don't figure it out, or while you wait for a fix, you can use a different window manager:
sudo apt install gnome-flashback
or
sudo apt install xfce4
or
sudo apt install plasma-desktop
or
sudo apt install cinnamon
or
sudo apt install lxde
or... if you really want to get to know your system
sudo apt install wmaker
or
sudo apt install icewm
Select our window manager from the login screen by clicking on the small Ubuntu icon

ps -eo pid,command >> withoutproblem.txt
andps -eo pid,command >> withproblem.txt
then do a diff on the problem.txt files.... alsopstree
