For more info, read the docs at
https://www.gentoo.org/doc/en/nvidia-guide.xml#doc_chap3_sect6

This ebuild installs a kernel module and X driver. Both must
match explicitly in their version. This means, if you restart
X, you must modprobe -r nvidia before starting it back up

To use the NVIDIA GLX, run \"eselect opengl set nvidia\"

To use the NVIDIA CUDA/OpenCL, run \"eselect opencl set nvidia\"

NVIDIA has requested that any bug reports submitted have the
output of nvidia-bug-report.sh included.

   Since Gentoo has critical dynamic libraries in /lib, and the static versions
   in /usr/lib, we need to have a "fake" dynamic lib in /usr/lib, otherwise we
   run into linking problems.  This "fake" dynamic lib is a linker script that
   redirects the linker to the real lib.  And yes, this works in the cross-
   compiling scenario as the sysroot-ed linker will prepend the real path.
