Below is picture of the display on bootup. Expected display output is 
overwritten by Angstrom screen

Expected Display output

The expected display output briefly appears but is overwritten by the 
Angstrom text based image. But occasionally the expected display appears. Then 
the dynamic widgets update the screen but the static information is not 
visible. The issues appears to be timing, and if the BBB can be forced to 
start the QT application after complete bootup of BBB that would suffices 
the current needs.
 
Application is been started as a service. Below is the content of the 
service file

[Unit]
Description=QTAccelerometer GUI
After=systemd-user-sessions.service

[Service]
WorkingDirectory=/home/root/projects/qt-projects
ExecStart=/home/root/projects/qt-projects/QTAccelerometer -qws
SyslogIdentifier=QTAccelerometer
Restart=on-failure
RestartSec=5

[Install]
Alias=display-manager.service
