Actually, reran yet again and (possibly) looking better.

Once my card reader stops acting oddly I’ll probably do a reinstall and start again from scratch. Maybe figure out where I went wrong.

No, I was actually using this setup guide here, which is less complete, but sure shows up in searches more often: https://github.com/MichMich/MagicMirror/wiki/Jessie-Lite-Installation-Guide

Now, however, I’ve gone through the setup you linked and and have ended up with:

Check current Node installation …
Node currently installed. Checking version number.
Minimum Node version: v5.1.0
Installed Node version: v6.4.0
No Node.js upgrade nessecery.
It seems like MagicMirror is already installed.
To prevent overwriting, the installer will be aborted.
Please rename the ~/MagicMirror folder and try again.

If you want to upgrade your installation run git pull from the ~/MagicMirror directory.

pi@pi:~ $ cd ~/MagicMirror
pi@pi:~/MagicMirror $ git pull
Already up-to-date.
pi@pi:~/MagicMirror $ cd $HOME/MagicMirror
pi@pi:~/MagicMirror $
pi@pi:~/MagicMirror $ npm start

Alright, so this may seem beyond simple, but I have to ask…

I’ve run through the install on a Pi2. The install gave me no problems. I go through the final reboot and…I’m looking at the Raspbian GUI.

Can anyone suggest the (clearly extremely obvious) step that I must have missed?
