I believe this is what I documented on https://wiki.debian.org/Xsession
If the wiki doesn't reflect your understanding of the scripts, then it's
possible that one of misread them, and we can work on getting the wiki
into a more accurate (or more clear) state.
I also used the Debian reference manual, linked from that page, and
"man Xsession", while trying to figure out how this stuff works. I did
not go through the extra steps of installing and removing various display
managers and desktop environments in order to reverse engineer them.
My dedication to this cause has limitations.
