Title:
  xrandr won't enable LVDS1 unless VGA1 is off

Status in X.org xf86-video-intel:
  Invalid
Status in xserver-xorg-video-intel package in Ubuntu:
  Incomplete

Bug description:
  Gnome-shell usually doesn't run on multiple monitors, even though it's
  configured in SystemSettings -> Displays

  "usually" because once in a blue moon it does.  So the hardware
  supports it.

  xrandr lists:
  LVDS1 connected (normal left inverted right x axis y axis)
     1366x768       59.9 +
  VGA1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 477mm x 268mm
     1920x1080      60.0*+

  (other resolutions cut from the output)

  gdm starts on both monitors.  As soon as I log in, LVDS1 goes off.

  I can enable the second monitor in SystemSettings->Displays, and even
  click on "keep configuration" but it doesn't activate.

  It's disabled in software somewhere.  I say that because the message
  tray at the bottom is in a different location when both monitors are
  active.  So there is a software detect-monitor-size that moves the
  message tray, and it's almost always where it would be for single
  monitors.

  Worked fine in Gnome-Shell 3.0.0.
