Public bug reported:
I have a notebook with dual graphic cards: Intel+Nvidia (handled by
nouveau). The miniDP port is apparently connected to nvidia since it
stops working when I use nouveau.modeset=0. I am able to start a Wayland
session when there's no secondary monitor connected; as soon as I
connect it to miniDP the wayland session crashes and falls back to the
greeter. The greeter won't even start Wayland session - it immediately
crashes back to the greeter. Workaround is to use the Xorg-based session
which works properly with secondary monitor.
