I recently did a fresh install for Ubuntu 13.04 64 bit. Everything was working fine until I tried to install drivers for my nvidia gt640.
I followed the steps in the answer to the question on this link askubuntu.com/questions/291199/ubuntu-13-04-installation-nvidia-driver
After this command sudo /sbin/lsmod | grep nvidia I didn't see the nvidia drivers loaded. After the following two commands sudo depmod -a sudo modprobe nvidia_current
I get the message that nvidia_current package can't be located.
Now after restating the computer, I login and all I can see is the wallpaper. Icons won't load and I don't think the wifi connects either because I can't seem to install anything from the terminal.
Any help is greatly appreciated
