Comment 111 for bug 1752053

I've upgraded from ubuntu 17.10 to 18.04 and I got the same issue.

When I boot on my laptop with a gtx 1070, I can see on my laptop screen and my monitor connected through a USB-C adapter the startup console starting all the modules. On the other hand I have the login screen working well on my external monitor (through HDMI).

It is important to notice that I cannot detect any of the two others display through the device manager or any command.

I believe that the monitor connected through HDMI only is using the integrated Intel GPU while my two other screens uses the nvidia graphic card.

This bug is definitively not fixed at all and it is astonishing to see that it has been marked as 'resolved' while a lot of users are still getting blocked from using their computer (personal or work...).
