Debian bookworm failure of awt.robot.createScreenCapture which works on buster and bunsenlabs Boron about linux

[6by9]

Bookworm is now using Wayland for the graphical environment. Does your Java class support Wayland backends, or only X11?
You can revert to X11 using raspi-config to test - Advanced Options/Wayland.

(Making your class support Wayland is not a kernel issue)

Wayland vs X11 is indeed the problem.

Reversion to X11 via raspi-config did, however, not allow me to move to Bookworm.
WTF is now that WayVNC shows uniform gray, disallowing headless operation.

I'll use Buster for my installs,
and check in a year or so
to see if they have fixed the java.awt stuff to allow compatibility with whatever Debian/Wayland is then RPi current.

Thank you for your quick and insightful response.

I'd recommend Bullseye over Buster. LTS ends on Buster on 30th June 2024, ie 5 months away.

WayVNC isn't going to anything useful against X11 as it is the backend for Wayland compositors using wlroots.

That's Debian's LTS. We have stopped updating our Buster packages long ago so running it is a massive security risk.

Bullseye it is. Nice catch.
