Public bug reported:
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):

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

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.
