My 20.04 install is suddently not booting into gnome. It just boots to the dreaded black screen with a blinking cursor. I can ctrl-alt-F* my way into a virtual console, but that's it.

journalctl -xe produces the following:

I've found some ideas for resolving this in the Arch boards, but that's it. Any ideas are appreciated.

Thanks!
