This bug was fixed in the package nvidia-graphics-drivers-updates - 304.64-0ubuntu0.1

---------------
nvidia-graphics-drivers-updates (304.64-0ubuntu0.1) precise-proposed; urgency=low

  * debian/dkms.conf.in,
    make-use-of-the-new-uapi-framework.patch,
    replace-VM_RESERVED-with-VM_DONTEXPAND-and-VM_DONTDU.patch:
    - Add support for Linux 3.7 (LP: #1075937).
  * New upstream release:
    - Fixed a bug that caused the EIZO FlexScan SX2762W
      monitor to remain blank when connected via
      DisplayPort.
    - Updated nvidia-settings to save and restore
      per-monitor color correction settings when RandR
      1.2 or later is available.
    - Fixed a bug that caused too many display devices
      to appear in the X Screen page of nvidia-settings
      when SLI is enabled.
    - Fixed a bug that caused applications to stop
      rendering or the X server to hang in Xinerama
      configurations when windows were moved, resized,
      mapped, or unmapped.
    - Fixed a bug that caused poor OpenGL performance
      on GeForce 6 and 7 PCI cards.
    - Fixed a bug in nvidia-settings that made it report
      the status of ECC configuration incorrectly.
    - Fixed a bug that caused the X server to crash if a
      display was put into DPMS off mode and subsequently
      reenabled while screen transformations are in use.
    - Fixed a bug that caused the X Resize and Rotate
      extension to be enabled when Xinerama is enabled.
      These two X extensions are incompatible and having
      them both enabled can confuse window managers such
      as KDE's kwin. RandR is now correctly disabled when
      Xinerama is enabled.
    - Fixed a bug causing OpenGL stereo applications to
      not work properly when using passive stereo modes 5
      through 9 on Quadro Fermi and newer GPUs.
    - Added support for the "Backlight" RandR output
      property for configuring the brightness of some
      notebook internal panels.
    - Fixed a bug that prevented the Ubuntu Unity launcher
      panel from unhiding (LP:# 1057000).
    - Fixed a bug that caused incorrect input
      transformation after resizing an NVIDIA X screen
      with xserver ABI 12 (xorg-server 1.12) or newer.
    - Fixed a bug that caused GLX to leak memory when
      Xinerama is enabled.
    - Fixed a regression in backlight control functionality
      on some notebook configurations.
    - Fixed a performance issue with recent Linux kernels
      when allocating and freeing system memory.
    - Fixed a bug that sometimes prevented the display
      device / X screen selection menu from being displayed
      in nvidia-settings.
    - Fixed a bug that prevented X driver gamma
      manipulation from working after a VT-switch on some
      configurations.
    - Added the option --output-file to nvidia-bug-report.sh
      to allow specifying a custom filename for the log file.
    - Fixed a hang when using OpenGL programs with some SLI
      Mosaic configurations on pre-Fermi GPUs.
    - Added sections to the Supported NVIDIA GPU Products
      list for NVS, Tesla, and VGX products.
    - Added support for the following GPUs:
      o VGX K1
      o VGX K2
      o Tesla K20c
      o Tesla K20m
