Black screen when installing Nvidia Drivers

I have just recently installed Ubuntu 13.10 and decided to install the necessary Nvidia driver:

sudo apt-get install nvidia-current

Then I reboot and find to have the black screen. I went into the terminal with Control-Alt-F1 and executed the following and rebooted:

sudo apt-get remove nvidia-current

But I still get the black screen. How can i fix this?

Try these commands on virtual console(ctrl+alt+F1),

sudo rm /etc/X11/xorg.conf
sudo apt-get purge nvidia*

sudo service lightdm restart
