Install / Uninstall NVIDIA Driver 340.24 On Ubuntu / LinuxMint

In this Tutorial I will tell you how to install the Latest stable version of NVIDIA Graphics driver 340.24 On Ubuntu 14.04 LTS / 12.04 LTS and LinuxMint 15 / 14 

This Version 340.24 released  on 8th July 2014 with a fix of  bugs.

Fixes in Version 340.24

• Fixed a bug that prevented 3D Vision stereo and ultra low motion blur modes from working on G-SYNC capable monitors in some cases.
• Fixed a bug that caused the "Allow G-SYNC" checkbox to be displayed in nvidia-settings even if the GPUs in the system are not capable of G-SYNC.
• Fixed a kernel crash when running some applications with IOMMU functionality enabled.
• Fixed a floating point exception in the OpenGL driver when running "Risk of Rain" under Wine.
• Made various improvements and corrections to the information reported to GL applications via the KHR_debug and ARB_debug_output extensions.
• Fixed a bug that caused GLX applications which simultaneously create drawables on multiple X servers to crash when swapping buffers.
• Updated nvidia-settings to report all valid names for each target when querying target types, e.g. `nvidia-settings -q gpus`.
• Added support for controlling the availability of Fast Approximate Antialiasing (FXAA) on a per-application basis via the new __GL_ALLOW_FXAA_USAGE environment variable and the corresponding GLAllowFXAAUsage application profile key. See the README for details.
• Fixed a bug where indirect rendering could become corrupted on system configurations that disallow writing to executable memory.
• Updated the nvidia-settings Makefiles to allow nvidia-settings to be dynamically linked against the host system's libjansson. This option can be enabled by setting the NV_USE_BUNDLED_LIBJANSSON Makefile variable to 0.Please note that nvidia-settings requires libjansson version 2.2 or later.
• Removed the runlevel check from nvidia-installer: the installation problems formerly associated with runlevel 1 no longer apply.
