The latest version of the Nvidia driver can be downloaded from Softpedia
Nvidia has just announced the immediate availability for download of the 319.49 certified version of its graphics driver for Linux operating systems.The new Linux display driver, 319.49, is actually an update for the Long Lived Branch, which means that it will probably get picked up in most of the repositories out there.
The main purpose of these drivers is to add support for a few new GPU chipsets, such as GeForce GT 740A, GeForce GT 745A, GeForce GT 755M, GeForce GT 625, GeForce GTX 645, GRID K340, GRID K350, NVS 315, and Quadro K500M.
As usual, a lot of other fixes and improvements have been implemented in drivers, alongside the support for the chipsets, but most of them are actually bug fixes.
The Long Lived Branch doesn't usually pick up a lot of new features, which are mainly reserved for the Short Lived Branch, or Beta, for a better word.
For example, the developers have fixed a bug that caused DisplayPort monitors connected to Quadro FX 3800, 4800, or 5800 to remain off after DPMS.
Also, Nvidia has repaired an issue that caused applications using CUDA-GL interop to crash when run on X servers with Xinerama enabled.
The company also added the new NVIDIA OpenGL-based Inband Frame Readback (NvIFROpenGL) library to the Linux driver package.
Accord to Nvidia, this library provides a high-performance, low-latency interface to capture and optionally encode an individual OpenGL framebuffer.
The newest desktop-oriented Nvidia GPU supported by these drivers is the GTX 780M and the oldest is GeForce 8800 GTX, which was launched back in 2006. Anything older than this and you will have to download the Legacy version of the driver.
