Accessing TFT attached displays on Raspberry Pi

[Nick Pratt]

I've spent some more time playing with fx config params for my Raspberry Pi
(arm HF 8u60).  I'm still unable to get any FX output on the attached TFT
display (Adafruit device plugged in to the GPIO pins such as:
https://www.adafruit.com/products/2315 (no touch) or
https://www.adafruit.com/products/1601 (with touch) ).

Is there any other logging that I can enable to assist with diagnosing the
issue other than what David suggested (attached below)

I'll happily send a committer with knowledge of the internals a loaner TFT
screen (these screens are only ~$30) if it facilitates getting this running
- being able to leverage the entire Java/FX SDK on a Pi+attached TFT would
be great.
