Sending to gnome-shell for review, given monitor does display output immediately after first configuration via Settings > Devices > Display (i.e. appears not driver/kernel issue).
** Description changed: - On Ubuntu 16.04 the login screen and system menu bar, ... is moved to - the monitor where the mouse pointer is located. On Ubuntu 18.04 login - dialog and system menues are restricted to the main monitor. + What is expected to happen is that with my computer turned off, when I + plug in my external VGA monitor into my laptop for the first time, and + boot up to the login screen, the display is in mirror mode and I can see + the login screen on both the built-in screen, and external monitor. - So if you have a notebook with defect lcd display you can work with it - using Ubuntu 16.04 and an external monitor, but you cannot work with - Ubuntu 18.04, because you are not able to login! - - This problem was also asked on: - https://askubuntu.com/questions/1031808/problem-with-login-screen-with-dual-monitor-on-ubuntu-18-04 + What happens instead is that the login screen is only shown on the + built-in screen.
