I have tried both bone-ubuntu-14.04.2-console-armhf-2015-06-11-2gb.img.xz 
 and bone-ubuntu-14.04.2-console-armhf-2015-07-08-2gb.img.xz images on a 
beaglebone black with a 4D 4.3" LCD cape, and can't get a display.

I know that the cape works because if I boot Angstrom I get a desktop. In 
this case xrandr reports the output as LVDS-0, which seems to be right.

Whatever I do on Ubuntu xrandr reports the output as HDMI-0, even when 
explicitly disabled. The video is coming out on the HDMI port.

During boot I see:

And I have edited uEnv.txt to what I think it should be.

Is it possible to get the LCD working on the current Ubuntu?
