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
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.
