This is an Intel i7-3537U integrated graphics setup. When I boot and log in and THEN attach a 4K monitor via DisplayPort everything works well. But when I attach the monitor and then boot, after logging in, Unity fails to start. It seems to be unable to allocate a OpenGL surface. Why the difference between startup and hotplug?
