OK  but  I'm not convinced.   I  commented out the "Use Events" like 
this shown below then rebooted the BackEnd.    I can't trigger the delay 
even with these commented out.   So I'm not convinced that the adding 
the Option fixes the problem.
Part of my /etc/X11/xorg.conf-----

    Option         "NoLogo" "1"
EndSection
