slackbuilds_ponce/system/nvidia-legacy173-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-legacy173-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.

Heinz Wiesinger, the author of the build script, has written a script called
nvidia-switch, which can be used to switch between the stock xorg driver and
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 --xorg	 <-->  switch to the stock xorg files
  nvidia-switch --nvidia  <--> switch to the proprietary nvidia files
  nvidia-switch --cleanup <--> switch to the stock xorg file and remove all
	symlinks created by nvidia-switch

No special steps are necessary when updating nvidia-legacy173-driver
from a previous package. If you update to a newer xorg, you do not have
to reinstall nvidia-legacy173-driver either. Just run
"nvidia-switch --nvidia" in that case.

Before uninstalling this package, it is important that you execute
'nvidia-switch --cleanup', which will switch back to the stock xorg files
and remove all links created by nvidia-switch before.
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/include/GL/{gl.h glx.h glxext.h glext.h}
  /usr/lib/xorg/modules/extensions/{libGLcore.so libGLcore.la libglx.so libglx.la}

This also requires the nvidia-legacy173-kernel package from SlackBuilds.org.
