I don't know if it is the same as my problem. But I had a problem with all full screen applications.
My Ubuntu is 14.04 32 bits using NVIDIA UNIX x86 Kernel Module  340.65, manually installed.

When my desktops loads it load in the full screen resolution (Full HD, 1920x1080). Then I want to lower my resolution to make a game run in a lower resolution when I switch it to full screen, if not it always run in 1920x1080, and that is what I don't want.
For example i switch my resolution to 1280x800. The resolution is switched OK, using nvidia-settings or xrandr (in command line). The same effect, it is not nvidia-settings related.

When I switch to lower resolution, the desktop and the panning desktop
(virtual desktop) appears to be the same. That is exactly what I expect.
But when I run any program, it does not matter if it is the game or not,
in full screen, the full screen is always in 1920x1080, I mean, the
program (a youtube video in chrome, a videogame, a video using mplayer,
using xine...), whatever application in full screen, always detect the
resolution being 1920x1080. Then, they don't switch the device
resolution by that, instead they run outside of the screen like if the
virtual desktop were still in 1920x1080.

Where can I specify the applications that the panned resolution and the
real resolution are the same?

May this be a bug in the NVIDIA driver? In XOrg?

If it is the same problem I can help sending logs and so. Just explain
me what you need and how to get that.

Title:
  Panning and full screen window size broken when using HDMI port

Status in nvidia-graphics-drivers-331 package in Ubuntu:
  New

Bug description:
  I'm running ubuntu 14.04 on a dell n7110.
  The laptop has hybrid graphics: an intel (sandybrindge) and an nvidia (525m), which is optimus powered.
  The built-in screen is wired to the intel card, while the HDMI port is rigged to the nvidia card.
  I have nvidia-prime installed, this is in the nvidia-mode.
  If logged in with default settings (HDMI being right-of built-in screen everything works fine.
  Then all hell breaks loose when trying to switch them, so the HDMI display is on the left.

  Two problems occur:
  The panning on the HDMI display is set to the size of the whole desktop, so when I try to move my mouse to the right of the screen (onto the built-in display) the screen on the HDMI display follows the mouse cursor, scrolling, rendering half the desktop invisible.

  The second problem is when I try to maximize a window on the HDMI
  display. It acts like only the left of the screen (so an area like
  300x1080px) is the whole display. Oddly the width of the display seems
  to be about the same as the height difference between the heigth of
  the two displays. If i set the top of the built-in display to be at
  the half-height of the HDMI display, then the full screen width
  increases. Note, that i can drag and move around my windows, but i can
  only resize (by dragging the side with the mouse) them in the invalid
  full screen area.

  I hope my description will be clear enough, if not I'll post pictures,
  or something.

  These problems occur with kde, too.
