More details:

There are a lot of discussion whether *dm should or not source
/etc/profile. in other words whether a graphical session is OR NOT a
login session. For example, Lightdm does not, but gdm3 does.

I run Debian Stretch, use some Trinity apps and I already set up
/etc/X11/Xsession.d/40x11-common_xsessionrc to source /etc/profile:

-----8<-----
# This file is sourced by Xsession(5), not executed.

if [ -e /etc/profile ]; then
    . /etc/profile
fi

#Source user defined xsessionrc (locales and other environment variables)
if [ -r "$USERXSESSIONRC" ]; then
   . "$USERXSESSIONRC"
fi
-----8<-----

But I wonder how Trinity tells its apps are in /opt/trinity/bin.
My only hope, is to add this to
/etc/X11/Xsession.d/40x11-common_xsessionrc (or add 40x11-trinity file
to all of my systems that run lightdm, should I???):

if [ -e /opt/trinity/bin ]; then
    . /opt/trinity/bin
fi
