jockey-backend crashed with SystemError: E:Sub-process /usr/bin/dpkg returned an error code (2)

[Taro]

I received this error when I finished installing a restricted graphics driver from ATI/AMD on my Asus 1215B red version. When I logged back in after restarting for the graphics card driver; that's when my screen started to have black and was not able to see Unity bar and the top bar.
