This is the proprietary binary video driver from NVidia for the X.Org X-server. This package does not include the kernel-module - it is a part of the nvidia-kernel package at SlackBuilds.org. Since this nvidia-driver conflicts with some files of xorg, it's a bit complex to install/uninstall the driver. However, installation of the nvidia-driver package itself backs up the conflicting files and puts the nvidia-specific files into place. Included is a script called nvidia-switch, which is used to switch from the xorg driver to the nvidia driver, but it will not edit xorg.conf for you; you have to do that manually. The nvidia-switch script is installed to /usr/sbin. Usage of nvidia-switch: nvidia-switch --install <--> install the nvidia files and save the stock xorg files. nvidia-switch --remove <--> remove the nvidia files and symlinks and restore the stock xorg files. You do NOT have to run nvidia-switch after installing the package. Note: x86_64 COMPAT32 enviroment is not supported. Before uninstalling or upgrading this package, it is important that you execute 'nvidia-switch --remove', which will switch back to the stock xorg files and remove all links created by nvidia-switch during installation. If you forget to do this, you'll have to do the switch manually, or xorg won't work on next startup. Here are the affected files: /usr/lib/libGL.so.1.2 /usr/lib/xorg/modules/extensions/{libglx.so libglx.la} or, for Slackware64, /usr/lib64/libGL.so.1.2 /usr/lib64/xorg/modules/extensions/{libglx.so libglx.la} Simply remove the dead nvidia symlinks and rename the saved '-xorg' appended files.
