Thanks for the help. So now I can invoke Java without the link errors, but my JavaFX app isnt appearing on the attached TFT screen ( Note: I can get 'x' to appear on the the Pi TFT screen by setting the FRAMEBUFFER variable prior to invoking startx so I know my TFT screen is setup and the right Kernel mods are enabled and applied)
Notwithstanding the error messages below, am I invoking Java correctly here : (based on the comments in https://javafx-jira.kenai.com/browse/RT-36960 ) pi@raspberrypi ~ $ java -Djavafx.platform=monocle -Dmonocle.screen.fb="/dev/fb1" -Ddispman.display=0 -Ddispman.layer=1 -jar JavaFXApp.jar Udev: Failed to write to /sys/class/input/mice/uevent Check that you have permission to access input devices Udev: Failed to write to /sys/class/input/event0/uevent Check that you have permission to access input devices Udev: Failed to write to /sys/class/input/input0/uevent Check that you have permission to access input devices Udev: Failed to write to /sys/class/input/mouse0/uevent Check that you have permission to access input devices If I run the above command as sudo root, then I dont see the errors printed, but still nothing on the TFT screen.
