Recently, I changed my OS kernel from 10.04 to 11.10 (bugs), but after doing it, the video driver for the 8400 GS disappeared (was there in 10.04). I worked out the same procedure I did to install it in 10.04, mainly,
sudo apt-get --purge remove nvidia-current sudo apt-get --purge autoremove sudo add-apt-repository ppa:ubuntu-x-swat/x-updates sudo apt-get update sudo apt-get -y install nvidia-current
but it didn't work even though the commands seemed to install the driver without problems. Right now my machine is working with the standard drivers, as shown.

Any suggestions to correct the problem? Thanks
Still waiting for additional help to resolve this. Did what was suggested below, but then, I got stuck.
