I am writing a script to output to external monitor automatically when it is
But now I have no idea about what name will be used for internal monitor in
some are "LVDS" and some are "DP1"

I want to parsing the xrandr output and remove the internal one. (xrandr |
grep -v " connected" | grep -v $INTERNAL_NAME)
then others will be external monitor.

So, does any methods to does which name will be used for internal monitor.

How does it achieve this function?
Does any event will be issued when I plug a external monitor?
