  * For "tidewater", the graphics card is GP107 [GeForce GTX 1050 Ti]
  * To find it on https://www.nvidia.com/Download/index.aspx drill down to:
    * GeForce > GeForce 10 Series > GeForce GTX 1050 Ti > Linux 64-bit > Production
  * You can also find the latest production version on https://www.nvidia.com/en-us/drivers/unix/

First make sure you do the following:

  yum install libglvnd-devel
  
__Notes from 26 Sept 2022__

When I tried to upgrade driver above NVIDIA-Linux-x86_64-418.56.run the X server crashed upon boot (noted by message upon first login "ABRT has detected 1 problem(s). For more info run: abrt-cli list --since 1664211525"

I re-installed the NVIDIA-Linux-x86_64-418.56.run file and accepted the defaults of including 32-bit libraries.  Believe I skipped DKMS as it gave an error and aborted installation.  It seems the RPM xorg-x11-server-Xorg-1.20.4-18.el7_9.x86_64 is giving the problem.

__Notes from 4 June 2022__

  * When I installed 515.48.07, I did not have the libglvnd-devel installed.  So I thought it was going to fail, but it actually kept going.  
  * It took about 3 minutes to finish.  
  * I answered Yes to update the X configuration (but where is the file?)
  * It said it was going to make a backup (but where)?
  * Rebooted, screen came up OK after a delay of a few seconds

To discover graphic card model that is installed:

  lshw -numeric -C display

To find current NVIDIA driver version:

  nvidia-smi


The following commands might be useful for updating the X server settings with NVIDIA graphics cards:
  nvidia-settings
  gdm-restart
