Trouble installing Nvidia driver

[Jessy09]

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

Remove the created dysfunctional xorg.conf file from the tty, like so:
sudo rm /etc/X11/xorg.conf

Retry with another version of NVidia drivers after ^^that^^ is done. If it still drops you to a tty, manually install the NVidia drivers by getting them from their main site.

Unfortunately, now I have a bigger problem...
Before I read your reply I tried to uninstall the driver with sudo apt-get --purge nvidia-current and now I get a black screen, no more terminal appears
What can I do in this case?

Hold down shift while your computer is booting up to access the GRUB2 menu.
Select the second option, I think its called Recovery Mode. Hit that and "Drop to root prompt."
Now delete xorg.conf as mentioned in my first post.

I did like you said, but I cannot delete the file; it says:
rm: cannot remove '/etc/X11/xorg.conf': Read-only file system


Edit:
I managed to solve the problem. It turns out that I could delete the file and now I can open the computer.

Thank you very very much
