OK, video is back now: apt-install ubuntu-mate-desktop fixed something. It was already installed, but doing it again tickled something. I logged into mater, and there was half a dozen core dumps of various components, and then everything started working. (I don´t actually use mate, it was just trying to see if issue was related to desktop environment in use.) I logged out, and now everything is now normal again.
now I can log in again, with the same environment I had before the problem. I´ve now commented out bionic proposed from /etc/apt/sources.list stuff looks ok. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1752053 Title: nvidia-390 fails to boot graphical display To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-390/+bug/1752053/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
