NVIDIA was very much clear when asked about this, and clearly stated that NVIDIA is not going to support Linux to the point, Windows and Mac would get. This issue of NVIDIA is not new and the users have been complaining for years regarding this. Where to find the drivers for NVIDIA GRID 2.0 vGPU and up, including M60, M10 and M6 drivers NVIDIA GRID: How to configure and deploy vGPU in VMware Horizon Desktops (Video) On VMware ESXI 5.1 using GPU passthrough, I cannot run the NVIDIA Control Panel and dxdiag shows svga adaptor.

NVIDIA has released alternate graphics drivers for OS X El Capitan 10.11.4. These are separate from the drivers Apple ships as standard, and should be considered experimental. These drivers have been known to solve OpenCL issues with certain applications, as well as providing better native GPU power management for certain devices.
NOTE: These drivers are currently the only method to get full acceleration for NVIDIA GeForce GTX 750, 750 Ti, 950, 960, 970, 980, 980 Ti, and TITAN X 'Maxwell' graphics cards. There are no current Macs with these cards, so support is absent natively in OS X.

If you've installed the drivers before, you may get a notification to update to the new drivers from the built in System Preferences pane.

How to Install the Web Drivers:
In order to use the alternate drivers on a CustoMac, you must first install the driver package. Also make sure to choose NVIDIA Web Driver using the standard menubar or system preference pane then reboot.
If drivers do not initiate, add nvda_drv=1 to Clover config.plist under Boot > Arguments.

Nvidia drivers

If you have an Nvidia graphics card on your system, then its recommended to install the official drivers provided by Nvidia. The proprietory drivers would utilise the hardware properly delivering full performance.

Installation is pretty easy and it uses a ppa repository. So you do not need to compile anything. However, make sure to follow the steps properly.

These steps would work on Ubuntu and close derivatives like Xubuntu, Kubuntu, Lubuntu and also Linux Mint and Elementary OS.

1. Find out your graphics card model

Use the lspci command to find out the model of your graphics card

Here its GeForce 210

2. Find out the right driver version for your graphics card

Visit http://www.nvidia.com/Download/index.aspx
Fill in the details about your graphics card and system and then click Search. On the next page, it should tell you the correct driver version with a download link and additional information.

For the above GeForce 210 card, it showed 331.67 as the correct driver which can be downloaded from the website. However we shall install the drivers from ppa to make things easier.

3. Setup the xorg-edgers ppa

The xorg-edgers ppa provides the very latest nvidia drivers. Run the following commands to set it up.

Now the ppa is setup and the package information is also updated.

4. Install the driver

Either you can install the driver directly by installing a single package containing 'nvidia' and the major version number ( 173, 304, 310, 313, 319, 331, 334 or 337).

Or you can enable it from the 'Additional Drivers' section. This is different on different Ubuntu flavors.

Synaptic package manager

If you have synaptic package manager installed, then go to Settings > Repositories > Additional Drivers tab and select the correct nvidia driver, and click Apply changes.

Ubuntu

If you are running Ubuntu unity desktop, simply launch the dash and search for 'driver'. Then click the application named 'Additional Drivers'. It will launch the same dialog box as shown above.

Xubuntu

Go to 'All Settings > Additional Drivers' and you should see a list of all available nvidia drivers ready to be installed. Select the correct driver and click Apply Changes. The new driver would be downloaded, installed and configured for use.

Kubuntu

Go to System Settings > System Administration > Driver Manager and select the nvidia driver there and click Apply.

After the installation is complete, reboot the system. You should see an option called 'Nvidia X Server Settings' in your applications menu. From there you can check information about the graphics card and configure it.

5. Verify the installation

The last thing to do is verify that the nvidia drivers are loaded and working. Run the lspci command again and this time the kernel driver should show nvidia

Check the last line which says 'kernel driver in use: nvidia'. This shows that nvidia drivers are now in action. Also check hardware acceleration with the glxinfo command

The OpenGL renderer string should be anything other than 'MESA'. Then it indicates that the hardware drivers are being used for hardware acceleration.

6. Nvidia settings tool

Linux Nvidia Driver Version

Nvidia would install a gui tool called 'Nvidia X Server Settings' somewhere in the menu. It can also be launched from the command line using the command 'nvidia-settings'. The tool shows miscellaneous information about the graphics card and the monitor connected, and also allows to configure various options.

The tool allows to configure the resolution of the monitor. If you are using dual monitors for example, then you can configure the monitor positions as well.

Removing the drivers

Incase anything goes wrong after the installation, like you are not able to boot Ubuntu, then try removing the Nvidia drivers.

Boot into the recovery console from the grub menu and then issue the following commands

Additional Notes

Many tutorials out there talk about blacklisting the nouveau driver. This is no longer necessary, since the nvidia driver would blacklist nouveau itself. This can be verified by checking the contents of nvidia driver files in the the modprobe.d directory.

Nvidia Mac Drivers

Note that the files 'nvidia-331_hybrid.conf' and 'nvidia-graphics-drivers.conf' have blacklisted nouveau.

Linux

To check information about the nvidia driver module, use the commands lsmod, modprobe and modinfo

The kernel module file for the nvidia driver is located at '/lib/modules/3.13.0-24-generic/updates/dkms/nvidia_331.ko'.

Note that it is a 'dkms' module which means, its loaded dynamically. Due to this the grub screen, the Ubuntu/Kubuntu splash screens would have a low resolution since at that time the nvidia drivers are not in effect, and whatever resolution is available via the VESA extensions, are used.
