[Arm-dev] xscreensaver missing from xfce group

I am trying to add xscreensaver manually.

I did a yum install xscreensaver and it also installed the following 
dependencies:

     1:xscreensaver-gl-base-5.39-3.el7.armv7hl
     1:xscreensaver-5.39-3.el7.armv7hl
     1:xscreensaver-base-5.39-3.el7.armv7hl
     1:xscreensaver-extras-5.39-3.el7.armv7hl
     1:xscreensaver-gl-extras-5.39-3.el7.armv7hl

And when I vnc to the system and wait, xscreensaver kicks in with the 
defaults.  But the control app is not in

applications > settings

And I can't figure out what to install.  greping for xscreensaver frm a 
yum list, I get:

cinnamon-screensaver.armv7hl 3.6.1-2.el7                  epel
cinnamon-screensaver-unsupported.noarch 3.6.1-2.el7                  epel
gnome-screensaver.armv7hl 3.6.1-14.el7                 epel
kdeartwork-screensavers.armv7hl 4.10.5-4.el7                 base
mate-screensaver.armv7hl 1.16.1-1.el7                 epel
mate-screensaver-devel.armv7hl 1.16.1-1.el7                 epel
xscreensaver.armv7hl 1:5.39-3.el7                 epel
xscreensaver-base.armv7hl 1:5.39-3.el7                 epel
xscreensaver-extras.armv7hl 1:5.39-3.el7                 epel
xscreensaver-extras-gss.armv7hl 1:5.39-3.el7                 epel
xscreensaver-gl-base.armv7hl 1:5.39-3.el7                 epel
xscreensaver-gl-extras.armv7hl 1:5.39-3.el7                 epel
xscreensaver-gl-extras-gss.armv7hl 1:5.39-3.el7                 epel

What of the above might be the control app?

thanks
