I'm hoping for some help on this. I looked been into several related problems, but none of them seem to work for me. I upgraded from Ubuntu 13.04 to 13.10 several weeks ago and it has been running smoothly. Two days ago (November 7) I had a software update, and yesterday I got a black screen after login.
I have an Nvidia graphics card, and in order to get Cairo dock and the Cube to work one needs the Nvidia restricted drivers. As far as I can understand from what I can find, it relates to the drivers. Many of the answers I found require some background knowledge which I don't have. Could someone give a newbie like myself a clean step-by-step introduction to how this is solved?
