When I boot, it goes straight into tty1. I have tried everything I could find online to solve this problem. I believe it has something to do with the Nvidia drivers. But reinstalling them in every possible way makes no difference. I am at a complete loss. My question is very similar to this question which never got answered: mountall: Disconnected from Plymouth
the boot ends with this:
mountall: Plymouth command failed mountall: Disconnected from Plymouth
