I experienced this as well within a VM running Ubuntu 19.10. I have an Nvidia GTX 1060 card. I started the upgrade process to 19.10 and mid way the screen went blank with only a blinking cursor. Rebooted the machine and I was greeted with the login page, but when I logged in there was a screen that said "something went wrong" and logging out started the process again.
Rebuilt the VM and this time disabled Automatic login before starting the upgrade. The upgrade went flawlessly and finished. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1845801 Title: Automatic login fails and then all subsequent logins fail.
