To get around my black screen issues, first I had to debug the Android 
image.  I had access to the android image via the serial console so I 
could see what was happening, sensorservice wouldn't start but would run 
if started manually.  You can see some info from the Android container 
by running logcat, though in my case there we no errors, I could just 
see from a console it wasn't running but I knew from the call in init.rc 
it had been started.

I ended up doing two things.

First, I added a startup call to sensorservice under the ubuntu init 
instead of Android by calling /system/bin/sensorservice directly. This 
prevented the crash at start, I think a delay might have been needed by 
I can't remember exactly.

Second, I still couldn't get any output from surfaceflinger.  I compared 
the source and the original Android version from my tablet was heavily 
modified to work with the powervr and merging would prove a bigger 
project than I had time for.  So I switched to mir and it came right 
up.  It crashes if I try to run two apps, or close the first app I start 
but it got me far enough along for POC.

Hope that helps.
