I have Ubuntu 18.04.1 installed on my computer. It recently (after an upgrade) stopped being able to boot up with two monitors. I can't even get to the grub menu.
I can still boot with 1 monitor, and my live 18.04.1 ubuntu dvd boots up fine with both monitors.
However, if I choose 'install', booting with the live dvd, when it gets to the installation type selection (thought I would safely reinstall working graphics over my data), it does not recognize any ubuntu installation on my computer.
What should I do to get my dual monitor system working?
