Bug Description

My Ubuntu is the version of 18.04, after system upgrading (I remembered with Kernel being upgraded), the screen will turn black before login window shows up.
PS: Currently I am only able to login to the system in the terminal instead of GUI. I don't know how to get related logs. If anyone needs logs for analysis, please tell me how I can collect the logs. Thanks!

UPDATE: Following information may provide help
This issue occurred on my laptop which has two video cards, one is independent nvidia GPU and the other is integrated Intel one. I think this might cause the problem because on my other laptop only has one nvidia GPU, no such kind of issue occurred (Although on that laptop, the nvidia driver is not at the version of 390).

I've same problem with nvidia 960 in combo with intel integrated card.
Even when I disable integrated card in BIOS, it doesn't help, but contrary making it default helps, but of course then system is using integrated card as main card.

I tried setting NOMODESET and WaylandEnable=false, but those didn't help.
Removing nvidia drivers and using noveau works.

Will also try replacing gdm with lightdm as suggested in
