I am using Intel HD 400 Graphics on a laptop.
When I logout, I get a black screen with no cursor or anything. I have to hard reboot the system to get into linux again.

I'm running Kubuntu in my Dell XPS laptop with dual monitors (laptop screen and a Samsung LCD monitor) and Nvidia's driver (NVIDIA-Linux-x86-340.46).
The problem is that I accidentally disabled the laptop screen at Display Settings and after that the screen went black. After reboot and login, the screen is still black and the only thing I can see is the mouse cursor.
I have an Alienware M17xR4 and have been running Fedora 20. The laptop has both integrated (Intel) and discrete graphics (Nvidia 680M). Yesterday I upgraded my laptop to Fedora 21. The upgrade went fine.
