Created a JavaFX FXML application using scene builder 1.1 named hi.jar
Application runs fine on windows machine
VP Option => JAVAFX_DEBUG=1 -Djavafx.platform=eglfb -Dglass.platform=Monocle -cp
-Dmonocle.screen.fb=/dev/fb0 /dev/fb0 = HDMI frame Buffer
-Dprism.verbose=true -Dprism.debug=true -Djavafx.verbose=true -Djavafx.debug=true
but on my system ls -lar /dev/fb* => /dev/fb0 = HDMI Frame Buffer
I tried different VM option conbinations and get following prominant errors :-
(1)Unable to load font (even though i have pango library installed and /usr/share/fonts has many .ttf files)
(2) not able to find or load class ( i am sure it find Main method but fails to load it)
(3) No setting found for javafx.platform=eglfb ( i expect jvafx to use /dev/fb0 HDMI frame buffer ,
also looked into javafx.platform.properties file but could not draw any conclusion)
Please drop me few words of advice
Thanks
