Login screen does not display on external screen

Asked by Akerbeltz on 2019-01-09

I have an external monitor connected to my Ubuntu laptop via a VGA cable. Before the upgrade to 18.04.1, when I fired up the laptop, the login screen would correctly display on the external monitor (as long as the cable was connected) but since the upgrade, the login screen only displays on the laptop screen. Once I enter the user password, it automatically flips to the external montior but not before.

This is probably a bug but I'll be jigswiggered if i can find a way of reporting a bug of this nature.

Akerbeltz,

i have similar problem...
and a work-around:

once you expect the login-screen to be displayed,
just move the mouse horizontal (left-right).

In my case the login screen pops up on the external screen too.

It is not the most ideal solution, but for me it is working fine.

Greetings,

It is a helpful workaround (if it works, I will try later) but it is still a bug that needs fixed. It's not reasonable for users to be able to guess at this workaround or even for them to have to use this workaround routinely.

Doesn't work. I've only just realized that it doesn't recognize the external keyboard either. The only peripheral it reconizes is the mouse and if I move that left-right, it causes the cursor to display on the external screen but the login remains on the laptop screen only.
