How do I install the new beta driver for Nvidia?

With Ubuntu before 12.04 I could do this:

1) Downloaded it from the site www.nvidia.com

2) Logout,

3) Move to tty1 (Ctrl + Alt + F1),

4) Stop lightdm or gdm (sudo service lightdm stop)

5) Remove any nvidia driver (sudo apt-get remove --purge nvidia-current nvidia-settings)

6) Cd into downloaded folder (cd ~/Downloads/)

7) Run the installer (sudo ./NVIDIA-Linux-***.run)

But this doesn't work anymore, i.e., after reboot I am presented with a very low graphic resolution (something about 320 x 400).
