Comment 12 for bug 1470862

I could get rid of the problem through upgrading to 15.10 and getting rid of fglrx - BUT! - I was greeted with a black screen at first My displays could not be detected. Via ssh I remotely logged in from another computer and completely removed my ati drivers, removed my Xorg.conf, and reinstalled Xorg (https://askubuntu.com/questions/68306/how-do-i-remove-the-proprietary-ati-drivers).

Trying that please be sure you have remote access to your computer or could find yourself stuck in front of a black screen!

So now I can agree Alberto Salvia Novella. My virtual consoles, my graphical session, and libreoffice (whose crashes had been the reason why I had to switch to fglrx) all work fine.
