I’m using a jetson nano which is pretty comparable to a raspberry PI.

At the moment when I run processing I get a:

> Cannot run sketch without a display. Read this for possible solutions:  
> [Running without a Display · processing/processing Wiki · GitHub](https://github.com/processing/processing/wiki/Running-without-a-Display)

The wiki is not helping, cause I want to run with a display.

I have tried both processing for Linux ARM as well Processing for PI.  
For the PI I get the following stacktrace:

I looked at multiple topics:

Here is a suggestion to use `export DISPLAY=` `":0"`  
or “:1” or “0:0” or “localhost:0.0”

If I set it to `:1` or `localhost:0.0` then I can’t even launch my code editor. If I set it to `:0` or `:0.0` then I can launch, but I will still have the Cannot run sketch without a display error.

Any help is welcome.
