I have laptop Lenovo y50 series having graphics nvidia graphics driver "Nvidia GeForce GTX 860M" of 4GB graphics memory. I followed the instructions given in the official Kali website.http://docs.kali.org/general-use/ins...-on-kali-linux to install the nvidia drivers. But when i installed it and rebooted the system, I get a Blinking Cursor with Black Screen.. So I also followed thistutorial which too did not help. Is there any solution for graphics driver?
