The attachment is the file generated by nvidia-bug-report.sh.

My graphic card is RTX A2000.

I have installed Ubuntu Desktop 20.04 on a HP workstation and I wanted to install nvidia driver to accelerate my Unity3D and ROS2 environment.

But I got black screen after rebooted.

I could use rdp on Win10 to login but I couldn’t see anything through the monitor connected to the nvidia graphic card.

I have tried to disable secure boot and install driver again but monitor couldn’t show anything.

I want to know the reason that result in this problem.
Is there any method to solve this problem?

After I changed a mini DP to DP cable and used a monitor with DP port , I solve this problem.

I have no idea why I could use adapter( mini DP to HDMI ) at first but I could not use this adapter anymore after I update the driver.

Maybe someone could leave comment below to describe the reason.
