Comment 2 for bug 969489

In case I wasn't clear, here is the window that pops up about half the times that I boot.

When this comes up, I hop to a tty, log in, and do 'start lightdm'. Then I have the bad X on :0 (with log files showing it tried to modprobe 'nv'), and the good X which I just started on :1.

When I don't get this popup, then lightdm/X start just fine and are running on :0.
