    How to Install / Upgrade Nvidia 319.49 in Ubuntu 13.04, 12.04, 12.10

    Last updated: August 26, 2013

    Nvidia DriverThe latest Long Lived Nvidia driver has reached 319.49, which added support for new GPUs and fix a few bugs. Here’s how to install or upgrade it in Ubuntu 13.04, Ubuntu 12.10, Ubuntu 12.04.

    What’s new in Nvidia 319.49:

  • Added support for the following GPUs: GeForce GT 740A, GeForce GT 745A, GeForce GT 755M, GeForce GT 625, GeForce GTX 645, GRID K340, GRID K350, NVS 315, Quadro K500M
  • Fixed a bug that caused DisplayPort monitors connected to Quadro FX 3800, 4800, or 5800 to remain off after DPMS.
  • Added the NVIDIA OpenGL-based Inband Frame Readback (NvIFROpenGL) library to the Linux driver package. This library provides a high performance, low latency interface to capture and optionally encode an individual OpenGL framebuffer. NvIFROpenGL captures pixels rendered by OpenGL only and is ideally suited to application capture and remoting.
  • Fixed a bug that caused applications using CUDA-GL interop to crash when run on X servers with Xinerama enabled.
  • Fixed a bug that could prevent some double-bit ECC errors from being properly reported.
  • Fixed a bug which could cause a blank screen when changing house sync settings on Quadro Kepler GPUs with Quadro Sync boards.
  • Fixed a bug that prevented nested loops with identical loop conditions in GLSL shaders from terminating correctly. This could cause hangs in applications such as Exa PowerVIZ.
  • Fixed a bug that resulted in corrupt texels when a previously empty texture image was specified with glXBindTexImageEXT. In GNOME 3, this caused gnome-screenshot to produce garbled window screenshots.
  • Fixed a bug that caused the X server to crash when querying the current mode of disabled displays.
