Unable to Configure External Monitors

Hi there,
I just installed Ubuntu Budgie 18.04. I have two external displays connected to my laptop. When I go to Displays and configure the alignment of displays ( Display no 1 is Laptop’s display, Display 3 is on top of Display 1 and Display 2 is in Portrait Right to the right of 1 and 3) and select apply, my Display 1 gets black and my configuration doesn’t get saved. I need to restart to see Display 1 again. Can anyone help me out in this? Thanks in Advance

Are you using Nvidia drivers? In some Ubuntu distros, I’ve needed to configure it in Nvidia settings too…
