Black screen with underscore after restarting ubnutu vm

Post by garse »

Hi, My host system is ubuntu 20.04, and I want to install a ubuntu 20.04 vm in virtualbox.

I Use an iso file which has worked before, and go through all setup and installation steps.
Little note: I choose "minimal install" as opposed to default which I have used other times.
After running through all installation steps, the machine tells me that it needs to restart. I restart it, and it boots back up.

When it turns back on, it has a purple screen for a few seconds, but then goes straight to a black screen with a single white underscore in the top left.

This has happened a few times now

might mean command line only, no desktop environment?

Also, if you ran updates, Ubuntu is known to go to black-screen when there is not enough disk space available to start the desktop environment. This happens on real PCs too. Web-search how to fix Ubuntu black-screen because of too little disk space, do what the web-search says to the VM, and please let us know what happened.

usually minimal install means that not a lot of stuff is installed on the machine. Like java, python text editor etc.
