unsetenv DISPLAY
pkill -f "Xvfb :30"
Xvfb :30 -ac &
run_my_qt_app -display :30
pkill -f "Xvfb :30"

Thanks for the suggestion, but no change.


FYI. A number of other random, non-Qt issues.
1 - How to insure the Xvfb goes away when I am done with it.
2 - The Xvfb tries to register itself globally with /tmp/.X30-lock,
     (which fails, randomly) but I just want a short lived local session.
