OctoPi with Octoprint 1.3.9
Waveshare 7" 1024 x 600
Touch UI

So I have everything installed now ... spend countless ours. The Screen boots up, Touch UI is loaded but the only thing is ... my touch input is mirrored to my Screen content.

Installed Screen with
wget http://www.waveshare.com/w/upload/7/74/LCD-show-170309.tar.gz
tar xvf LCD-show-170309.tar.gz
cd LCD-show/
chmod +x LCD7-1024x600-show
./LCD7-1024x600-show
cd LCD-show/
./LCD7-1024x600-show 180

You might try reading through the script contents for Adafruit's PiTFT helper. I know that in my case, it asks questions about where you want the screen to mirror (or not) and then does actions based upon that.

Actually, it looks like it's been moved to here as adafruit-pitft.sh. As you can see, there's a lot going on.
