== Introduction ==
NVIDIA have proprietary graphics drivers for Linux under binary blob. The alternative open source driver is {{Package|x11-drivers/xf86-video-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:
 
[http://www.nvidia.com/object/IO_32667.html 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.


<console>
<console>
###i## echo “>x11-drivers/nvidia-drivers-340” >> /etc/portage/package.mask
###i## echo "media-libs/freetype infinality" >> /etc/portage/package.use
###i## emerge -uN fontconfig
</console>
</console>


=== The required kernel options ===
== Advanced configuration ==
 
=== Fontconfig ===
{{kernelop|desc=
==== Default configuration ====
[*] Enable loadable module support
}}
{{kernelop|desc=
[*] 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.
{{kernelop|desc=
Device Drivers --->
      Graphics support --->
            <*> Support for frame buffer devices --->
                  <> NVIDIA Framebuffer Support
                  <> NVIDIA Riva support
}}
 
{{tip|An alternative is to [[uvesafb|uvesafb]] framebuffer, which can be installed in parallel with nvidia-drivers }}
 
== Installation ==


Upgrade and/or configure <tt>VIDEO_CARDS</tt>  variable to <tt>nvidia</tt> in <tt>/etc/make.conf</tt>. This will serve to while you are installing the Server X, the correct version of nvidia-drivers to be provided for you.
<console>
<console>

{{note|Installing to the driver with the option in '''gtk''' use flags will make it installed the <tt>media-video/nvidia-settings</tt> which is a graphical tool for monitoring and various settings for your video card}}
Same as default configuration except:

<console>
<console>
###i## emerge x11-drivers/nvidia-drives

=== Testing your Video Card ===
Same as default except:
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.
<console>
<console>

Those variables can be overridden on a per-user basis by either redefining them in a startup file (such as <tt>~/.bash_profile</tt>) or by sourcing the <tt>/usr/lib/ft-settings.sh</tt> script with the desired style in parameter (you can, of course, source the script from a startup file).


=== Integration with X Server ===
usage: source ft-settings.sh <style>
When your X server is installed find, and there's <tt>/etc/X11/xorg.conf</tt> you can run the nvidia-xconfig which will set in xorg.conf to identify the video card among other possible configurations.

Install the packages

Linux font quality is a chronic issue, by default fonts configuration far from ideal look. This can solved by rebuilding media-libs/freetype with the infinality USE flag, which applies the infinality patch set. Infinality patches were previously available only in the lcd-filtering overlay and have now been merged into the main Funtoo portage tree.

Freetype

Freetype can be configured through environment variables (see /etc/env.d/99lcdfilter for a list of the variables and their description). Those variables can be overridden on a per-user basis by either redefining them in a startup file (such as ~/.bash_profile) or by sourcing the /usr/lib/ft-settings.sh script with the desired style in parameter (you can, of course, source the script from a startup file).

usage: source ft-settings.sh <style> 

Possible styles:

  sharpened    - Full stem snapping, tweaks, and Windows-style sharpening  
  infinality   - Settings used by Infinality

LibXft

Only legacy programs still use libXft. The default configuration is defined in /usr/share/X11/app-defaults/Xft. It can be overriden on a per-user basis in the ~/.Xresources or ~/.Xdefaults files:

   ~/.Xdefaults 
Xft.antialias:  1

Xft.dpi:        96  
Xft.hinting:    1
