Title:
  Ubuntu 14.04 forgets Display Settings from monitors.xml / xorg.conf
  (Dual-Screen Setup)

Status in “xorg” package in Ubuntu:
  Confirmed

Bug description:
  Steps to Reproduce:
  1. Install Ubuntu Gnome14.04 on a freshly formatted PC with 2 screens
  2. Using "Additional Drivers", install latest Nvidia driver (331)
  3. Modify screen settings (e.g. change position of 2 screens as depicted in attached Screens_good.gif)
  4. Turn secondary screen off and back on - OR - reboot
  5. Observe that screen settings have been reverted

  Actual Results:
  Ubuntu forgets the screen settings made in either NVidia-settings or Ubuntu's own "Displays" tool. The screen settings are reverted to the default (screen 2 to the right of screen 1) after reboot or when turning the second screen off and back on.

  Expected Results:
  Ubuntu should apply the user's defined screen settings when the second screen is turned on.

  Notes:
  The test PC has two devices connected to a GeForce GTX 680 (Gigabyte GV-N680OC-2GD) card:
  1. Samsung SyncMaster screen via DVI
  2. Yamaha RX-V 661 5.1 surround receiver via HDMI (recognized by Ubuntu as a second screen)
  Encountered in Ubuntu Gnome 14.04, 64 bit
  Encountered with NVidia drivers 331, 331 update and 304 (legacy)

  Reading Xorg.0.log, one can see that the user's desired settings are
  actually applied more than once (exerpts):

  [     5.252] (II) NVIDIA(0): Validated MetaModes:
  [     5.252] (II) NVIDIA(0):     "DVI-I-0:1920x1200_60+0+1080,HDMI-0:1920x1080_60i+1920+0"
  [     5.252] (II) NVIDIA(0): Virtual screen size determined to be 1920 x 2280
  [     5.275] (--) NVIDIA(0): DPI set to (93, 95); computed from "UseEdidDpi" X config

  At the very end, an unknown process takes over and reverts the
  previous desired settings to the undesired default (line 3):

  Attachments: screenshots of desired screen settings (Screens_good.gif) and default screen settings (Screens.gif)
  This issue occurs regardless of whether the user makes the desired settings in Ubuntu's "Display" tool or NVidia-Settings.
  This issue persists even after specifically saving the desired settings to xorg.conf using NVidia-Settings.
