When I go from my graphical session to a virtual console by Ctrl + Alt + F i (with i in 1 - 7 and 9-12) I see a completely black screen. Only on F8 I see the GUI. Not even a blinking coursor on the others. When I enter anything, I can't see anything.
What is the problem and how do I fix it?

edit: I tried the first steps suggested on http://forums.linuxmint.com/viewtopic.php?f=42&t=168108 and the problem seems to be the framebuffer.
I did this:
This has been an issue that has been an annoyance with Nvidia proprietary drivers for two or three years, and has kept me away from Ubuntu-based distros for some time. Finally, on the Nvidia forum, I found the workaround I'd been looking for. The problem arises with Nvidia proprietary drivers (Nouveau doesn't show this behavior): when you push ctrl-alt-F1, you get only a black screen or, at best, a flashing cursor that does nothing. The problem apparently, has to do with the way the framebuffer in implemented and this needs to be disabled. To see if this is the problem, first you need to make a couple of minor modifications to /etc/default/grub - but first, make a backup!
$ sudo cp /etc/default/grub /etc/default/grub.bak
Now edit the file by entering
$ sudo pluma /etc/default/grub
in the editor, uncomment the lines
by removing the
#. Save the file and run undate-grub to implement the changes
Now I have (a low resultion) tty working again :-)
