I am running qml-compositor on wayland-0, and (the unpatched) weston (1.7) works very well, I can also run maynard.

With the patched weston and orbital, I get:

Backtrace stopped: previous frame identical to this frame (corrupt stack?)

I don't have any X11 running, and I disabled pulse and alsa, so I don't know why it's trying to start pulseaudio.

I'm not sure what could be the problem, it seems to crash in the driver probably, but the last frame is missing debug symbols. You could try running it with valgrind, it may tell something useful.

It's trying to start pulseaudio because you have an autostart desktop file for it, either in /etc/xdg/autostart/ or in ~/.config/autostart/.

Hi @mihailescu2m if your VGA compatible controller is about Intel Corporation balabala ;-) please have a look at https://bugs.freedesktop.org/show_bug.cgi?id=89689 and here is the patch https://bugs.freedesktop.org/attachment.cgi?id=114500
