Hello! I am new to this forum, so I hope that I am posting this in the right place.
I installed Linux Mint 12 KDE and then I wanted to install the Nvidia driver. I managed up until a point where from the menu I could open a window in which i had driver settings. When I opened that window, a message told me to restart the X server by typing sudo xconfig (or something like that) from the terminal.
I entered that in the terminal and then a full screen terminal appeared and I don't know how to exit it. I think it's the tty terminal and I tried pressing Ctrl+Alt+F7 but nothing happened. I restarted the computer and then a black window with white letters appeared, like the one which appears when I shut down the computer. I pressed Ctrl+Alt+F3 but that only led me back to the tty terminal.
Can somebody please help me because I really don't know what to do
