** Description changed:
- 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.
+ If I boot up with two external monitors connected, the login screen
+ doesn't show up on any 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.
+ The laptop display shows the mouse cursor on a blue screen, the HDMI
+ monitor shows a blank blue screen, and the VGA monitor shows no signal.
- This monitor configuration worked fine with this computer in Trusty.
+ WORKAROUND: Use 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`.
+ WORKAROUND: Boot with only one external monitor connected.
