My laptop is Lenovo x220( hd4400 & cpu i5-2520M), I've installed 10.12 successfully. My question is: If I boot without -v flag, it will not startup successful, black screen. If I add -v flag, it will startup successfully! Why?? As my understood, -v just turn on verbose, it will affect nothing. But the fact isn't what I thought. So, I wanna to know why?? What is the deep reason?? How can I fix it??
