Blank screen after booting on Ubuntu 18.04

We have a lambda workstation from 2019. After a recent reboot, all we get is the “Asus” logo and then a blank screen.
We are currently running Ubuntu 18.04, and are still able to SSH into the machine and run jobs on it, we are just not getting any monitor output.

I do not recall making any updates, but nvidia-smi shows: NVIDIA-SMI 455.28 Driver Version: 455.28 CUDA Version: 11.1. Are we running an incompatible driver version, and is this what’s causing the no output?

If so, is there a way to quickly downgrade to the latest compatible driver versions?

Thanks in advance,

Can you run sudo apt-get update -y && sudo apt-get upgrade -y. You have an older version of the driver vs the current Lambda Stack.

Did anybody on the system install a different driver that caused this issue?
