Screens go black after entering password at log in screen

[philly1ms]

Installed Ubuntu 20.04.3 LTS and I'm having an issue at the log in screen. The Ubuntu boots just fine but once I enter my password both screens go blank and into low power mode. Laptop still running but I have to do a hard shutdown. Once it starts backup it works the second time. If I open the lid to the laptop it's also blank. I made sure to be running the latest Nvidia Driver. Any suggestions? Thank you

You say both screens go blank. Is this laptop also connected to a monitor? What happens if you load Ubuntu with the monitor not connected to the laptop?

I am curious about this issue because I have just ordered a laptop which I shall use along with my present desktop machine. There will be times when I will want to connect the laptop to the monitor. It will be a new experience for me.

My laptop is connected to 2 external monitors. Both monitors plus the laptop screen go blank once I enter my password at the log in screen. I fixed the issue for now by allowing it to boot right into the desktop without a password. If that wouldn't have worked then I would have tried disconnecting both external monitors to see what would happen. Maybe there will be a better solution in the future. I don't really need to have it password protected for now.

My GPU is a Nvidia Geforce RTX 3080
