Host: macos 10.14, Guest: ubuntu 19.04; screen is completely black

Post by icumara »

I have my disco dingo virtual machine running and I can ssh into it.
However, I need the GUI and I am only presented with a completely black screen.
I rarely use this vm, so I'm not sure when it happened.
I did just upgrade from 6.0.10 to 6.0.12. Perhaps that is related?
I am uncertain how to go about debugging the issue.

We need to see a complete VBox.log, from a complete VM run, where the problem occurs:
  • Start the VM from cold-boot (not from a paused or saved state) / Observe or recreate the problem / Shutdown the VM (force close it if you have to).
  • With the VM completely shut down (not paused or saved), right-click on the VM in the VirtualBox Manager and select "Show Log".
  • Save only the first "VBox.log", ZIP it and attach it to your response. See the "Upload attachment" tab below the reply form.
