I see, that the real final executor is in the very-last file in the whole sequence:
/etc/X11/Xsession.d/99x11-common_start:
exec $STARTUP
and STARTUP is set, according to file existence, to one of the
x-session-manager
x-window-manager
x-terminal-emulator
but preferably to: ~/.xsession if it exists
So it seems I need to run one of these three standard executables in my .xsession and surround it with my process execution and termination by PID.
Thanks again!
