Summary: NVIDIA accelerated graphics driver
- Install the X.org driver, OpenGL libraries, XvMC libraries, and VDPAU libraries
- Install nvidia-settings with support for GTK+ 2
- Install nvidia-settings with support for GTK+ 3
- PaX patches from the PaX project
- Install additional tools such as nvidia-settings
- Install the Unified Memory kernel module (nvidia-uvm) for sharing memory between CPU and GPU in CUDA programs
Unfork Tree is Live!The "unfork" tree is now merged into the main Funtoo Linux tree, and Funtoo Linux is now using shards for core packages, x11 (including media libraries), KDE, GNOME, python and perl.
OpenSSH 7 Disables DSA Keys By DefaultPlease be aware of this important change to avoid getting locked out of your Funtoo server.

NVIDIA Linux Display Drivers
NVIDIA have proprietary graphics drivers for Linux under binary blob. The alternative open source driver is Package:Nouveau Video Drivers (Open Source).
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:
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.
# 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.
Device Drivers ---> Graphics support ---> <*> 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
Upgrade and/or configure VIDEO_CARDS variable to 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.
# nano /etc/make.conf VIDEO_CARDS="nvidia"
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
# emerge x11-drivers/nvidia-drives
When the installation is complete run modprobe nvidia module to read kernel memory.
# lsmod | grep nvidia
If an update before remove the old module
# rmmod nvidia # 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.
$ glxinfo | grep direct $ direct rendering: yes
Loading at boot
To automate the loading of the module when you boot your system, add nvidia in modules variable.
# nano /etc/conf.d/modules modules="nvidia"
Integration with X Server
When your X server is installed find, and there's /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.
Section "Device" Identifier "nvidia" Driver "nvidia" VendorName "NVIDIA Corporation" BoardName "[Name] [Model]" EndSection
Enabling NVIDIA Support
Include the use flag in nvidia in /etc/make.conf so due to applications that make use of this advantage may withdraw.
# nano /etc/make.conf USE="nvidia"
As a requirement, make sure that the Xorg server is not in use during this change. To enable OpenGL and OpenCL.
# eselect opengl set nvidia # eselect opencl set nvidia
