This installation procedure will likely be simplified further in the future, but for the moment you will need to download the NVIDIA FreeBSD Graphics Driver archives from the NVIDIA website, extract them to a temporary location of your choice, and run the following from the root of the extracted directory hierarchy:
% make install
This will compile the NVIDIA FreeBSD kernel module, install it,
and kldload it. It will also remove any conflicting OpenGL
libraries, and install the NVIDIA OpenGL libraries. The
/dev/nvidia
device files will be
created (unless the system is using devfs), and your /boot/loader.conf
file will be updated to
automatically load the NVIDIA kernel module on boot, as well as the
Linux ABI compatibility module should you not have it compiled into
your kernel.
