Nvidia driver are giving black screen

[hokori616]

I got a huge problem, since I earlier today installed a Nvidia graphics driver (I do not remember the exact name) that was recommended by Ubuntu 10.04 that is installed on my Lenovo B560 laptop so do the screen go completely black after that the GRUB has loaded and the splash screen should come up, id est when the drivers should start to load. I have read on the internet that it is possible to solve through terminal mode, alt+ctrl+F1, however my ctrl buttons do not work which make the whole situation more complicated.
Is this solvable or is the only way to get rid of this unfriendly driver to reinstall the OS?

Thanks on beforehand

Edit: Running recovery mode also result in the same blank screen.
