Slackware Notes:

This version of NVIDIA driver is taken from the original site:
NVIDIA-Linux-x86_64-304.51.run
or
NVIDIA-Linux-x86-304.51.run

The package should already contain the nvidia.ko kernel module.
If not or if you recompile or upgrade your kernel, you must recompile the module
using the script:
/usr/share/nvidia-linux/makekernelmodule.sh
Be sure that nouveau driver is not loaded (or reboot to ensure; the best is 
running in runlevel 3).


These drivers conflict, for libGL and libglx, with the preinstalled drivers 
(xorg-server and mesa packages).
The libglx.so will be backupped in
/usr/lib/xorg/modules/extensions/libglx.so-prenvidia
or
/usr/lib64/xorg/modules/extensions/libglx.so-prenvidia

If you remove the nvidia-linux package, you MUST restore this file and launch the
command "ldconfig"

If during a system upgrade (to current or patches) the 'mesa' or 'xorg-server' 
packages will be upgraded, you MUST rerun the nvidia-linux postinstall script:
# cd /
# bash /var/log/scripts/nvidia-linux-*


This package add the files /etc/X11/xorg.d/nvidia.conf to configure your driver.
If you use the nvidia-xconfig tools to reconfigure the driver, you must delete it.



This package remove the nvidia libvdpau, so you need to install it (open libvdpau
or nvidia-vdpau).


You may need to reconfigure the X server.
By default you have a minimal configuration in /etc/X11/xorg.conf.d but you may
remove it and lauch nvidia-xconfig to start a new /etc/X11/xorg.conf and next
nvidia-settings to tune it.
