Has there been any fix for this yet?

The workaround  in #5  works most of the time, but has some issues.
I don't have gnome.

My setup:
Notebook with internal 1920x1080 screen,
1920x1200 Screen attached via hdmi
1280x1024 screen attached via usv graphics card

Title:
  Can't disable panning on multiple monitors

Status in xorg-server package in Ubuntu:
  Confirmed

Bug description:
  System:

  Dell laptop E6520 with two graphic cards:

  00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) (prog-if 00 [VGA controller])
  01:00.0 VGA compatible controller: NVIDIA Corporation GF119M [NVS 4200M] (rev a1) (prog-if 00 [VGA controller])

  I have 3 monitors connected through docking stations, DP-0 and DP-1
  connected to Nvidia card and VGA-1-0 connected to Intel card.

  I'm usind nvida-331 driver and nvidia-prime:

  nbr@nbr-nb:~$ dpkg --get-selections | grep nvidia
  nvidia-331					install
  nvidia-common					install
  nvidia-libopencl1-331				install
  nvidia-opencl-icd-331				install
  nvidia-prime					install
  nvidia-settings					install

  I can setup correctly this triple-head config with Monitor Settings in
  Ubuntu Control Panel, but this enable panning as per xrandr output:

  nbr@nbr-nb:~$ xrandr -q | grep conn
  VGA-0 disconnected (normal left inverted right x axis y axis)
  LVDS-0 disconnected (normal left inverted right x axis y axis)
  DP-0 connected 1280x1024+0+0 (normal left inverted right x axis y axis) 376mm x 301mm panning 2560x1024+0+0 tracking 4240x1050+0+0 border 0/0/0/0
  DP-1 connected primary 1680x1050+1280+0 (normal left inverted right x axis y axis) 433mm x 270mm panning 2960x1050+1280+0 tracking 4240x1050+0+0 border 0/0/0/0
  HDMI-0 disconnected (normal left inverted right x axis y axis)
  DP-2 disconnected (normal left inverted right x axis y axis)
  DP-3 disconnected (normal left inverted right x axis y axis)
  LVDS-1-0 connected
  VGA-1-0 connected 1280x1024+2960+0 376mm x 301mm

  and it seems there is no way to disable it (even issuing xrandr with
  --panning 0x0+0+0 option to DP-0 and DP-1 has no effect).

  This was working correctly after a undock/dock of the laptop, maybe an
  update broke config since it has always showed problems with
  undock/dock, but a reboot always cured the situation. Now it can't be
  setup like initial config anymore (three indipendent monitors with no
  panning and windows moving around all monitors).
