Having problem while using external monitor on parrot os

[user116351]

I just want to use both the screens like normally we do when i’m home I can connect to the external monitor & when i’m out i can use the laptop screen. But i’m not able to use the laptop screen but the external monitor is working fine. Suppose the external monitor is not available to me in that case I won’t be able to see anything on my laptop because as soon as parrot loads up the laptop display goes blank
