Comment 0 for bug 1870779

I have the reproducible effect with Ubuntu 20.04 beta that I'm able to login right after installation, but after a few reboots a black screen is displayed after login.
I'm able to switch to a tty and tried to collect information with ubuntu-bug, but I am not sure if that help. I'm happy to provide further information if needed.
I reinstalled Ubuntu a couple of times, the behaviour is always the same. 19.10 works with any problem.
