slackbuilds_ponce/system/nvidia-legacy340-driver

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.

Installing 32-bit compatibility libraries is available. If desired, do:
  COMPAT32="yes" ./nvidia-driver.SlackBuild

Several useful utilities are included: nvidia-xsettings, nvidia-smi, and
nvidia-settings. Please refer to the Nvidia documentation and man pages
for details and usage.

For CUDA/OpenCL to work after reboot, include the following line in your
/etc/rc.d/rc.local:
-------------8<---------------
# Create missing nvidia device nodes after reboot
/usr/bin/nvidia-modprobe -c 0 -u
------------->8---------------

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. NOTE: Although nvidia-switch is
aware of a COMPAT32 environment, its use therein is not supported.

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.

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[64]/libGL.so.1.2
  /usr/lib[64]/xorg/modules/extensions/{libglx.so libglx.la}

Simply remove the dead nvidia symlinks and rename the saved '-xorg'
appended files.
