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.
Working on RHEL 6 (gnome)

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 just upgraded from F18->F19 which apparently went fine. But now I want to login, and after this I only see "fedora" in the bottom of the screen, and a pipe as mouse cursor. Apart from this, the screen stays black, no matter which desktop I select (LXDE, XFCE, Mate, Gnome). Reboot doesn't help either.
I have installed Ubuntu 13.10 64-bit on my desktop PC, and it seems it's not working properly. I have freezing while typing, the virtual console is not available, if I try go to it my screen is freezing, also the cursor leaves a trace on the screen.
I have tried to install Nvidia graphics drivers (from offsite, and from xorg repositories), but after it my Ubuntu doesn't boot.
Whenever I try to switch to one of the text terminals (by hitting Ctrl-Alt-Fx) or try to log out (either by Ctrl-Alt-Backspace or the graphical logout menu or xfce4-session-logout), all I get is a black screen, with no cursor, nor any text whatsoever.
I've looked through logs but haven't noticed anything relevant.
I've waited for a couple of minutes for it, but nothing happened.
