Cannot eliminate screen blank, lock or saver or whatever it's called...

Hi all, I'm running CentOS 7. When the machine is left alone for a few minutes, a screen saver or blanker or something comes up with a clock and date on it. You have to swipe this to get back to the desktop. I'm trying desperately to get rid of this so that it never comes up. No matter how long I am away from the machine, I don't want the desktop to go away. I've tried the following and have managed to eliminate the need to sign in again, but I still can't seem to get rid of the clock/date screen:

[1] Turned off the lock screen in settings, security.
[2] Executed: setterm -blank 0
[3] Created: /etc/X11/xorg.conf t contain the following:

  Section "ServerFlags"
     Option    "blank time" "0"
     Option    "standby time" "0"
     Option    "suspend time" "0"
     Option    "off time" "0"
 EndSection

[4] Ran the following:

  #!/bin/sh
 export DISPLAY=:0.0
 xset s off
 xset s noblank
 xset �dpms

Of course, it goes without saying that any help is greatly appreciated. I'm getting desperate here.

I have xscreensaver -no-splash running...
