I installed the Nvidia GT 520M using the following commands:
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install nvidia-current
and then I restarted my computer and it logs in fine, however there is no menu bar, no side menu or anything, just my Desktop. I can open folders on my Desktop, however I cannot close these. I can open the terminal. Here is an what my screen looks like (I can take screen shots)
This is my whole screen. What do I do to get the GUI functioning properly again? Also, I am running Ubuntu 13.04
