Reinstalled DirectFB with the video driver set to *none*. Ran the sample
JavaFX 8 program with similar errors showing up again:
cmd : cd '/home/debian/NetBeans_Projects//JavaFX_Test';
'/home/debian/ejre-1.8.0_fx/bin/java' -Dfile.encoding=UTF-8
-Djavafx.platform=directfb -jar

This time when running the sample program locally a *segmentation fault*
message appears. Thought it might be useful to display the frame buffer
info (via *fbset -i*):
Frame buffer device information:

Just realised that I installed an experimental version of DirectFB from the
1.7 branch. Will try a stable one from the 1.6 branch. Hopefully that will
do the trick.
