Introduction
NVidia have proprietary graphics drivers for Linux under binary blob. The alternative open source driver is nouveau.
Preparing to Install
Hardware compatibility and driver versions
Currently there are five meta versions of nVidia Linux drivers each of which supports a specific group of GPUs. To check the type of driver that is related to your video card, check the link on this page of the official nVidia:
www.nvidia.com/object/IO_32667.html
If you have identified as your driver version 337.25, for example, you need the mask(s) driver(s) latest(s) to which you want to install.
root # echo “>x11-drivers/nvidia-drivers-340” >> /etc/portage/package.mask
The required kernel options
[*] Enable loadable module support
[*] MTRR (Memory Type Range Register) support
To we made a successful compilation of the legacy nVidia driver, we set before the removal of the native framebuffer drivers into the kernel in order to avoid conflicts for x86 and AMD64 processors, in this case.

<*> Support for frame buffer devices >
<> nVidia Framebuffer Support
<> nVidia Riva support
An alternative is to uvesafb framebuffer, which can be installed in parallel with nvidia-drivers
Installation
Upgrade and/or configure VIDEO_CARDS variable "nvidia" in /etc/make.conf. This will serve to while you are installing the Server X, the correct version of nvidia-drivers to be provided for you.
Installing to the driver with the option in gtk use flags will make it installed the media-video/nvidia-settings which is a graphical tool for monitoring and various settings for your video card
Emerging the package
root # emerge x11-drivers/nvidia-drives
When the installation is complete run modprobe nvidia module to read kernel memory.
root # lsmod | grep nvidia
If an update before remove the old module
root # rmmod nvidia root # modprobe nvidia
Testing your Video Card
To test your video card run the glxinfo program, which is part of the mesa-progs package. This will check if direct rendering is enabled.
user $ glxinfo | grep direct
Configuring
Loading at boot
To automate the loading of the module when you boot your system, add nvidia in /etc/conf.d/modules.
Integration with X Server
When your X server is installed, the existing logo /etc/X11/xorg.conf you can run the nvidia-xconfig which will set in xorg.conf to identify the video card among other possible configurations.
/etc/X11/xorg.conf Section "Device"
Identifier "nvidia"
Driver "nvidia"
VendorName "NVIDIA Corporation"
BoardName "[Nome] [Modelo]"
EndSection
Enabling support nVidia
Include the use flag in nvidia /etc/portage/make.conf so due to applications that make use of this advantage may withdraw.
Enabling OpenGL/OpenCL
As a requirement, make sure that the Xorg server is not in use during this change. To enable OpenGL and OpenCL.
root # eselect opengl set nvidia root # eselect opencl set nvidia
