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`.
