NVIDIA Driver Version: 390.138, external display not detected

Hi there!
I am having trouble with the driver version 390.138.
The external displays are not detected.
I am currently using ubuntu 20.04.1 with Quadro 1000M.
Also tried installing lightdm but it did not help.
The bug report output ran as root : nvidia-bug-report.txt - Google Drive
.

Thank you for your help in advance!
