Clean install Ubuntu 10.10 trouble with Nvidia driver for 8400M GT

To day i pass all day trying to install Ubuntu 10.10 with difficulty, after install the recommended driver and reboot the only thing i get is a black screen, this was the same driver on Ubuntu 10.04 and I did not have problems with it. My solution to this was to use the version 173

then I saw the whole forum for the solution to this, for me this was very easy, the links to the help:

 ( Add the x-swat PPA: https://launchpad.net/~ubuntu-x-swat/+archive/x-updates)
 (Use your package manager (apt-get, aptitude, whatever) to update your software. Then, run Additional Drivers applet again to activate the Current (recommended) driver. This should update both the video driver and xorg to the PPA versions. Reboot, again.)


This will update the driver to the last current version 260.19.12.
