HI,  
I’d like to execute processing sketches from RaspberryPI via FadeCandy ([https://github.com/scanlime/fadecandy](https://github.com/scanlime/fadecandy)) that uses OPC (Open Pixel Control protocol) to display them to a leds Matrix from Adafruit.  
But Processing from CLI always complains about X11 required .  
Is it possible ?
