Title:
  Using nVidia proprietary driver 361.42 yields black screen

Status in xorg package in Ubuntu:
  Incomplete

Bug description:
  # Context

  Selecting nvidia driver using software-properties-gtk.
  Install goes ok. No longer observing bug 
https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-361/+bug/1553554

  Hardware is Asus n551jk laptop. nvidia driver worked on same hardware
  with Ubuntu 14.04.

  # Expected

  Correct display with better performance and 3D support.

  # Observed.

  No immediate effect, although GUI says driver is used.

  On next boot, no graphical login was observed. Screen was just black.

  Normal boot again yields same result. Waiting half an hour did not
  yield any more result.

  I logged in on a text console and ran "ubuntu-bug" to generate a bug
  report that I kept until I had a working X again.

  Booting in rescue mode I finally managed to get to a X session (which
  is not the usual nouveau setup, for example xbacklight does not work,
  full brightness hurts my eyes, output is no longer named "eDP1" but
  "default").

  # Additional information

  Will try to switch to proprietary driver 340.96 as suggested by
  software-properties-gtk.

  I guess all other needed information is included in bug report
  (generated by ubuntu-bug).
