Below are the results.

First, I checked to make sure the screensaver was running. It was.

tcameron at case:~/Desktop$ xfce4-screensaver

** (xfce4-screensaver:3447853): WARNING **: 10:34:38.141: screensaver 
already running in this session

Next, I checked to make sure it's enabled. It is.

tcameron at case:~/Desktop$ xdg-screensaver status
enabled

Next I checked to see if the appropriate .desktop file existed. It does. 
The screensaver DOES work right after I log in or reboot, it only stops 
working after a while. The OnlyShowIn=GNOME;MATE; section caught my eye. 
I don't *think* it's a problem, but I'm open to suggestions.

tcameron at case:~$ cat 
/usr/share/applications/screensavers/xscreensaver-glmatrix.desktop
[Desktop Entry]
Name=GL Matrix
Comment=The 3D "digital rain" effect, as seen in the title sequence of 
"The Matrix".  See also "xmatrix" for a 2D rendering of the similar 
effect that appeared on the computer monitors actually *in* the movie.

OnlyShowIn=GNOME;MATE;

Just to check, I looked at the xfce4-screensaver.xml file. It looks correct.

tcameron at case:~$ cat 
.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-screensaver.xml
<?xml version="1.0" encoding="UTF-8"?>

<channel name="xfce4-screensaver" version="1.0">
   <property name="saver" type="empty">
     <property name="mode" type="int" value="2"/>
     <property name="themes" type="empty">
       <property name="list" type="array">
         <value type="string" value="screensavers-xscreensaver-glmatrix"/>
       </property>
     </property>
     <property name="idle-activation" type="empty">
       <property name="delay" type="int" value="1"/>
       <property name="enabled" type="bool" value="true"/>
     </property>
     <property name="fullscreen-inhibit" type="bool" value="false"/>
   </property>
   <property name="lock" type="empty">
     <property name="saver-activation" type="empty">
       <property name="delay" type="int" value="5"/>
     </property>
   </property>
</channel>

Again, after a reboot or a fresh login, the screensaver works as 
expected. It fails after some time, hours or days.
