Public bug reported: I'm running bionic on a Lenovo X230 laptop. It works fine to boot it with either my hdmi monitor or my VGA monitor. It also works to attach the VGA monitor after booting and logging in with the HTMI monitor.
But if both are connected while I boot, the graphical login prompt never appears, and just the mouse appears in the laptop window on a blue screen, with the HDMI monitor showing a blank blue screen, and the VGA monitor getting no signal. This monitor configuration worked fine with this computer in Trusty. I ran apport-bug to report the problem, and chose the first option: "Display (X.org)". I'm not positive what I'm running, but note that after booting and getting both monitors plugged in and running after login, I see both an Xwayland process and an Xorg process. I suggest also changing apport-bug to appropriately reflect that wayland is somehow involved, and I hope that the included debug info will include any appropriate wayland info. I note that it does seem to be possible to get some info via `apport-bug xwayland`.
