I've customized my distribution; the intentions are to run Qt either to the 
XServer with no display manager, or directly off the frame buffer.

I did start with the default Angstrom 3.8.13 kernel and root file system.  
I don't believe I customized the kernel at all with the exception of 
modifying the FTDI serial driver, therefore not really related to any 
display.

My setup is Beaglebone Black with the 7" Touch LCD CAPE.

How I've modified the boot up is that I do run XServer, but do not run a 
display manager, instead I'd run my Qt application as part of my xinitrc.  
Right now it just happens to run an xterm as I develop my Qt app.  This all 
happens at boot, if I were to disable loading the XServer, then my display 
would merely show the Angstrom login prompt at the command line.

I happened to attach a USB keyboard and from my XServer it did not work; 
I'm not thinking that maybe I can just go to command line and maybe that 
keyboard will work.

The way I talk to it now is via the serial 232 console on J1, or I can ssh 
to it, but mainly I do use the serial console.

A draft Qt application was created, a few buttons and I can activate those 
buttons if I manage to get the right touch; appears right now that touch 
calibration is almost random, probably because it never occurred at all.

So I have xinput_calibrator as well as the script, they were already 
there.  I do see the documentation that by default it should come up when 
you run your board in the out of the box mode, but as I'm saying, I'm far 
away from that point.  I can of course unplug my microSD card and run the 
default provided Angstrom and also erase the calibration file to cause that 
to calibrate again.  This thought as I draft here is giving yet another 
idea.

Problems/Thoughts/Questions:
- Wondering if I can get to be able to run xinput_calibrator, right now it 
always tells me that it cannot connect to the XServer; my attempt have been 
to try and run it from my serial console or via ssh offering it arguments 
like "--device :0" and no joy.  Also have run ssh with -X and -Y options 
and similarly not been able to get xinput_calibrator to agree that it can 
run.
- Given my problem of no keyboard running while my XServer is running 
that's sort of a bummer, I will check my system log to see if there's 
anything obvious; because potentially with that one xterm running I may be 
able to run xinput_calibrator from that terminal and it will then see the 
XServer.
- My thinking on calibrating under the default Angstrom build is that I can 
grab the calibration file and copy it to my SD card so that when I boot it, 
it will consider that data to be the valid calibration.  This last one is 
actually my thoughts towards my next, first step.

If anybody sees some sort of other solution path, I'd be interested to read 
your inputs.  Sorry if these thoughts are somewhat disorganized; I think 
you can tell that as I write this I'm getting new ideas during composition.

Best Regards,
