Boot the daily image.

Get a black screen.

Go to tty1 - lightdm has started - running sudo service lightdm status echoes start/waiting

Return to tty7 and the login dialogue has now appeared

using lubuntu desktop i386 20141014, i have no problems. don't have an amd64 machine handy at present.

another successful test:

image: Xubuntu i386 20141016
vm: VirtualBox 4.3.18-96516~Ubuntu~raring
host: Kubuntu 14.04

boots straight to the try/install screen without having to flip virtual terminals or anything.

i'm guessing this is either a host hardware conflict of some kind or perhaps the issue is related to the amd64 image. no amd64 machine handy to test right now.

Lubuntu 64 bit image, no issue. (Nvidia drivers)

Ubuntu GNOME Utopic Unicorn 20141022.1 RC amd64 and it is happening with me - same as the video on comment #9

I am running Xubuntu 12.04.5 and Oracle VM version 4.1.12_Ubuntu and found this one while I was testing the RC of Ubuntu GNOME.

i386 of the same build works just fine and couldn't produce that on i386.
