I am running a fresh install of Ubuntu 16.04 (alongside Windows 10) on a brand new(ish) Toshiba laptop. Everything was working fine until I installed Bioshock Infinite from Steam and when I ran it I got an error saying that my graphics driver did not support OpenGL 4.1. My graphics card is Nvidia 930M.
So I did a search and found this post: Steam and OpenGl 4.1. I followed the instructions there and installed the repository ppa:
After the restart all menus were simply black rectangles, the Terminal window was completely black and there were large black borders around windows. This problem appears on several other posts. I followed all of the instructions in these (such as remove Nvidia and reinstall, remove the above repository, etc.). But to no avail. I am also surprised how little help this problem has received from the community. (See for example: Black border in all menus and black terminal after installing Katoolin).
