It's the root. I usually follow the breadcrumbs from there: typically
it sources things from the user directories. That's the mechanism to
allow per-user configuration. As an example, I want a per-user Xmodmap:
in /etc/X11/Xsession.d/80x11xmodmap (which didn't exist) I have:

  # 2015-01-10 tomas: why did they steal my xmodmap?
  # Snarfed from <http://forums.debian.net/viewtopic.php?t=77008>
  
  # This file is sourced by Xsession(5), not executed.
  
  SYSMODMAP="/etc/X11/Xmodmap"
  USRMODMAP="$HOME/.Xmodmap"
  
  if [ -x /usr/bin/X11/xmodmap ]; then
      if [ -f "$SYSMODMAP" ]; then
          xmodmap "$SYSMODMAP"
      fi
  
      if [ -f "$USRMODMAP" ]; then
          xmodmap "$USRMODMAP"
      fi
  fi

...the rest is in $HOME/.Xmodmap.

Debian ships those things partially disabled (as was the case with
Xmodmap), so I enable them in /etc first and put the relevant per-user
configuration bits in the user's home, of course.

This should work independently of the desktop, AFAIK. But I can't tell
from first-hand experience.

Yes, this is to be expected, since in the former case it inherits the
settings of the shell and in the latter case it inherits whatever the
X session/the desktop environment has.
