Pi5 running bookworm full desktop install, fully updated with Camera Module 3
I am trying to use this code which is based upon an example in the manual.If I boot up with a screen and keyboard connected and run the code from a terminal it works. If I boot up headless and connect via ssh from my desktop and run the code it fails with "Failed to reserve DRM plane". Here is the output -
How can I fix it?
