@sdetweil When I ran the install it asked me if I wanted to disable screensaver and I said yes but my screen was still going black over night. I would have to CTRL-Q out then it would run again automatically after a few seconds. Thought installing the screensaver and disabling it would help. Will see after tonight.

That fixed it thank you.

I agree but that was all I did.
Installed then disabled making the screen go blank then sudo reboot.

After reboot I get the error I posted above.

I installed
apt-get install xscreensaver

After I installed the screensaver to stop the screen going dark my MagicMirror stopped working.

I now get this error.

magicmirror@2.10.0 start /home/pi/MagicMirror
./run-start.sh
