I am now running a Beaglebone Black with a 4Dsystems 4.3" LCD.

The LCD  is all black.

Created my own image, based on arago-qt5-test-image

This does not add libgles-omap3, which seems to be needed.

Also built the qtbase-examples.

The resulting filesystem did not find the modules, but after depmod -a, 
this is OK.

root@beaglebone:/usr/share/qt5/examples/widgets/widgets/calculator# lsmod
Module                  Size  Used by
bufferclass_ti          5405  0
omaplfb                11414  0
pvrsrvkm              175499  2 bufferclass_ti,omaplfb

I can run several Qt applications, but: Screen is all black.

I do not get a splash screen,  and I did not change any device-tree files,
so I assume this is the problem.

Anyone has a working device tree file for this?

Romber Nelson and some other people mention that the 3.12 kernel used is 
not compatible with the advanced capes like LCDs.
Do I need to revert to the 3.8 kernel?
