Title:
  gpu-manager writes wrong driver in xorg.conf fro nvidia-prime

Status in ubuntu-drivers-common package in Ubuntu:
  Confirmed

Bug description:
  The driver for the intel part of xorg.conf should be modesetting
  instead of intel, see also: https://askubuntu.com/questions/580693
  /black-screen-when-in-nvidia-mode-after-updating-to-kernel-3-13-0-45

  From what I can see this is set here: http://bazaar.launchpad.net
  /~ubuntu-branches/ubuntu/trusty/ubuntu-drivers-common/trusty-
  proposed/view/head:/share/hybrid/gpu-manager.c#L1588

  I am seeing this on a trusty system with nvidia-346 driver on both
  3.16 and 3.13 kernels.

  The end result of doing this worng is that system boots up with black
  screen.

  As a workaround I have commented out gpu-manager in /etc/init/gpu-
  manager.conf (when starting lightdm) and in /sbin/prime-switch (when
  stopping lightdm).
