I have installed Processing 3.5.3 on Raspberry PI4. 3.5.3, because there is a specific version for ARM. When I used programs with P3D (3D) an error code is send on black window. Same Processing version on Windows 11, with sames parametres, programs works correctly.  
error message : failed to add service- already in use ? Could not run the sketch ( Target VM failed to initialize). Any way to solve my problem ? Thank you

If I remember correctly following “experimental graphics” in this doc might help

@Eta14 not all P3D sketches will work on RaspberryPI4 but many will. The original support for processing was for the RaspberryPI3 [Getting Started - Processing for Pi](https://pi.processing.org/get-started/) and most of the technical information in the link @micaut supplied is totally irrelevant to RaspberryPI4 but that’s the latest official support. I’ve successfully installed an alpha version of processing4 on ManjaroArm see here [Processing in style with Java 11 - #40 by monkstone](https://discourse.processing.org/t/processing-in-style-with-java-11/13776/40). NB: The official alpha3 version does not work!!! In principle there’s no reason why it won’t also work on RaspberryPI OS, because my [PiCrate](https://ruby-processing.github.io/PiCrate/) (ruby-processing for RaspberryPI) works on both operating systems.

@Eta14 I can get the `service in use?` message if I use legacy video driver, you need to run raspi-config `Advanced Options` then `A2 Gldriver` and enable `G2 GL Fake KMS` then reboot. VC4 full KMS not available on RaspberryPI4 yet. This only applies to RaspberryPI OS, Manjaro Arm it is enabled by default…

Thank you Martin. I did this operation yesterday. Naoto Hieda have suggested to read a technical documentation, day before. So I modified configuration. Now Processing work correctly in most exemples with P3D. I have solve an other problem, Raspberry PI4 can be connected to 2 screens. Before yesterday, probably after an update or upgrade, only one sreen displayed data. Now the two ones dispay differents images.  
Again thank you for your help.

Thank Naoto for suggestion, I read technical documentation. Modification of raspi-config, advanced option, GL driver, set to G2 (Fake KMS). From severals days, I had lost the second sreen, now both ones are working. Thank you for your help.
