Ubuntu not booting normally & cannot enter Terminal

Hello, I have a Dell Precision 7530 with a dual boot of Windows 10 and Ubuntu 18.04. I have an Nvidia Quadro P2000 video card installed and have installed the Nvidia-460 diver successfully a couple of days ago. However, when I installed an application that is based on docker and rebooted the system yesterday, I found that I could no longer enter the system. All I got is black screen and pressing Ctrl+Alt+F1/F6/F7 receives no output.

There are several solutions I have tried, which are all failed:

  1. Remove quiet splash parameter
  2. Replace quiet splash with nomodeset
  3. Replace quiet splash with noveau.noaccel=1
  4. Add nomodeset
  5. Replace quiet splash with noapic noacpi nosplash irqpoll

I do have recovery mode and an older kernal listed in grub, but both of them failed and the only two lines of output is:

Loading ubuntu 5.4.70-generic…
Loading initial ramdisk…

It’s not my first to experience problems booting into ubuntu, my past problems can be found here. In short, I didn’t find out what’s wrong with my system and all I did was reinstalling ubuntu, but I really don’t want to do this again.

The NO.1 problem I face right now is how to get into the terminal and generate nvidia-bug-report? @generix

I might try using SSH to login remotely but I can’t guarantee that will work.

Thanks for your help!
