Title:
  nvidia-settings can not detect any real displays/monitors (trusty)
  (Optimus Laptop)

Status in “nvidia-settings” package in Ubuntu:
  Confirmed

Bug description:
  OS: Ubuntu Gnome 14.04 Trusty (latest upgrade)
  Hardware: Asus U36JC
  Graphic Driver: nvidia-331

  I have opened a bug #1296020 (Non-existent display detected in both intel driver and nvidia driver).
  Except the non-existent display issue, nvidia-settings can not detect any real displays. The only display/monitor it can detect is the non-existent one. I think this should be a different bug for nvidia-331. 

  For "xrandr -q" output, please refer to bug #1296020. nvidia-settings
  becomes useless now, it can not detect the built-in display and it can
  not detect any new external display. It can only detect the non-
  existent CRT-0 (VGA-0). Gnome control center --> Display can detect
  all displays. (but it fails to rotate external VGA display. not sure
  if this is another bug or not).

  I will attach two screenshots for nvidia-settings and gnome-control-
  center --> display.

  NOTE: due to the bug #1296020 and gdm flickering issue, I have added
  the following section to xorg.conf:

  Section "Monitor"
      Identifier "VGA-0"
      Option "Ignore" "True"
  EndSection

  AND, xorg.conf is auto-generated by some package. I never created it
  manually. It might be generated by gpu-manager (I was told).
