So here is how I was able to fix my issue with the screen saver. I started this project following the tutorial from here:
https://github.com/MichMich/MagicMirror/wiki/Jessie-Lite-Installation-Guide
When you get to the Disable the ScreenSaver portion of the article, instead of changing the autostart file under
/etc/xdg/lxsession/LXDE/autostart
You should modify the autostart file under ~/.config/lxsession/LXDE/autostart
sudo nano ~/.config/lxsession/LXDE/autostart
Comment the first 3 lines (using a #), then add the same three lines listed in the tutorial. The final autostart file after all modifications should look similar to:
#@lxpanel --profile LXDE
#@pcmanfm --desktop --profile LXDE
#@xscreensaver -no-splash
@xset s noblack
@xset s off
@xset -dpms
Once that is done, follow the instructions to modify the lightdm.conf file:
sudo nano /etc/lightdm/lightdm.conf
[SeatDefaults]
xserver-command=X -s 0 -dpms
Save the changes, reboot your raspberry pi (I am using an RPi3), and the screen saver is gone for good. Hopefully this helps someone else having the same issue.
