Bug Description

---
On Cosmic dev, I can't use my displayport monitor after logging in to gdm3. It works for login (displays the login page) after the VT switch to the session it becomes black. Using CTRL+f1, etc doesn't also show the console even in my VGA monitor.
Devices:
* Thinkpad x230t with Intel 3rd gen core processor and graphics unit.
* Laptop LCD.
* 4k monitor plugged in to display port.
* 1080p monitor plugged in to vga port.
The graphic's memory is not enough so I have to turn off the Laptop LCD to power 4k and 1080p monitors. When it boots, I can see the login screen in the 4k monitor.
To be able to login, what I do is unplug 4k monitor when booting and logging in. Once session is active, I plugin the 4k monitor.
Thank you for your work/help.

This would be related to both:
* The new feature of gdm3 exiting/restarting when you switch VTs; and
* Other recent changes to VT handling in Ubuntu 18.10 (gdm3, mutter).
I had hoped these issues would be fixed with bug 1786872 and bug 1786872 :(
