Yet more RPI OF problems …
in the RPI install guide in section " Tips for 0.11.0 / Raspberry Pi 4"
you can install Xorg and run from commandline without full desktop:
startx ./polygonExample – -s off
polygonExample compiles fine but launching via this method fails due to server shutting down.
See this error but I still see it if I run openbox.
XDG_RUNTIME_DIR not set in environment.xinit
I installed openbox and can run starts to get a window manager and use RunRelease to launch file, which works but not what I want.
