The screen will suddenly turn black, and after a few seconds, the LightDM login screen appears. All unsaved work is lost of course. A clean install of 15.10 did not help, the problem persists. It happens absolutely randomly. I haven't been able to figure out any pattern related to time or specific user interaction that would cause this, except that I believe the crash is always triggered by some kind of input device action, i.e. mouse click or key press. The system won't crash if I don't actively do any work.
