This is the kernel-module needed by the proprietary binary nvidia driver. You also need the nvidia-driver package from SlackBuilds.org. To build the package for a kernel different from the running one, start the script setting the KERNEL variable as in KERNEL=4.6.3 ./nvidia-legacy470-kernel.SlackBuild A default config file is placed at /usr/share/X11/xorg.conf.d/10-nvidia.conf to make sure that X loads the nvidia module. If you need to make changes, move that file to /etc/X11/xorg.conf.d/ and edit the copy. You do not need this file at all if you have a proper and complete xorg.conf. The xf86-video-nouveau-blacklist package from /extra is required. The Nvidia 390.xx series will be supported through December 2022.
