======kmod-nvidia======
The **kmod-nvidia** package provides the NVIDIA driver kernel module (nvidia.ko).  To determine which driver your graphics card requires, please use the [[nvidia-detect|nvidia-detect]] utility.

The **nvidia-x11-drv** package provides the proprietary NVIDIA binary OpenGL X11 display driver files. This package will be installed as a requirement for kmod-nvidia.

To install kmod-nvidia, run:
<code>
# yum install kmod-nvidia
</code>

If you don't know which graphics card you have, run:
<code>
# yum install nvidia-detect
# yum install $(nvidia-detect)
</code>

After installing / updating the nvidia package, users are advised to **reboot their system**. Simply restarting X may not suffice, one needs to drop out of X, remove and reload the nvidia kernel module and restart X. For most end users, a reboot will be simpler. 

/* For the complete list of graphics cards supported by the **legacy** drivers, please refer to the following Nvidia documentation:

http://www.nvidia.com/object/IO_32667.html

For the **current** (550) driver, please see:

https://www.nvidia.com/Download/driverResults.aspx/223426/en-us/
*/

**If you used Nvidia's binary installer** \\
Users who have installed the driver by running the binary installer provided by Nvidia are advised to //uninstall it before attempting to install kmod-nvidia//.  Run the same script that was used for the installation by adding a %%--uninstall%% flag.  For example (adjust the name appropriately):

<code># sh ./NVIDIA-Linux-x86_64-550.54.14.run --uninstall</code>

**If you get a black screen upon reboot** \\
If you are faced with a black screen and do NOT have ssh access to the system, then one way to obtain a usable CLI is to reboot the system, stop at the grub/grub2 menu, edit (i.e., "e") the first kernel command line, add " 3" to the end of the kernel command line, and continue the boot to multi-user.target (runlevel 3, non-GUI).
