[Bug 1373397] Re: External monitor scrolling huge virtual buffer with laptop monitor

Just to confirm, I get the exact same behaviour when the external screen
is placed to the left.  The external display pans to duplicate the
desktop of the built in display.  Also, maximising windows causes the
window to span across both monitors.

Title:
  External monitor scrolling huge virtual buffer with laptop monitor

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

Bug description:
  - Dell XPS 14Z
  - NVidia GeForce GT 520M + Intel i915
  - nvidia-prime
  - Mini-DP connected to DVI of external HP LP2065 monitor
  - Ubuntu 14.04
  - nvidia 331 drivers (from Ubuntu repos)

  If my external monitor is located at top of laptop screep:
  - when I move the mouse cursor to the bottom of the external screen, it scroll the entire screen to show the laptop screen inside the external monitor, just like a huge virtual screen.

  If my external monitor is located at right. everything is fine, there
  is no scrolling.

  I'm not sure this is a bug. I searched the web and could not find a
  way to properly fix this. Since the behavior change with the sideways
  arrangement I guess is a bug.
