It might be an “18.04 thing”: External monitor not detected on Ubuntu 18.04. I’ve never experienced it upgrading to 18.04 or 19.04 but I’m already using LightDM.
I have a close but not identical system. Dell AW 17R3, I-7 6700HQ Intel HD 530 iGPU, nVidia GTX 970M GPU. Besides comments above, I’ll share my xorg.conf in hopes it might help:
$ cat /etc/X11/xorg.conf

Ignore the DP-1-1 monitor section. It is only for my 3rd monitor which has a finicky; 4K TV, or Thuderbolt 3 adapter, or cable or all three.
