My laptop is a Dell XPS 15 with a Nvidia video. I tried both drivers nouveau and nvidia with the same result. I can reproduce the error ALWAYS, when I put the laptop to sleep it wont resume, I can see the power light and the keyboard backlight turning on as if it will wake up, but then just a black screen. I cannot even switch to a terminal (Ctr+Alt+F1), the only solution it to restart. The problem is not only when sleeping, it also happens when the screen is turned off by Power Management.
