On Debian systems all is handled via the /etc/X11/Xsession.d directory.

For RHEL et al I see this in the /etc/x2go/Xsession script:

"""
        CK_XINIT_SESSION=
        if [ -x /usr/bin/ck-xinit-session -a -z "$XDG_SESSION_COOKIE" ]; then
                CK_XINIT_SESSION="/usr/bin/ck-xinit-session"
        fi

        # At the time of integrating X2Go Xsession support for RHEL6 / Fedora
        # the Xsession stuff in Fedora/RHEL6 seems to be a little mess.
        # The proposed strategy is to have Xclients.$WM.sh files in
        # /etc/X11/xinit/Xclients.d. Currently, only wmx uses this mechanism.
        # As it is a described but rather unused ,,standard'' we will  
not support it
        # in X2Go for now, but leave it here as a reminder...

        # XCLIENTS_D=/etc/x2go/Xclients.d
        #if [ -d "$XCLIENTS_D" -a -x  
"$XCLIENTS_D/Xclients.${XSESSION_EXEC}.sh" ]; then
        #       exec -l $SHELL -c "$CK_XINIT_SESSION $SSH_AGENT  
$XCLIENTS_D/Xclients.$1.sh"
        #fi

        # switchdesk support is also totally deprecated in RHEL, but  
we leave it here
        # as a reminder, as well, in case we need it in the future  
for special setups...
        #if [ -x "$SWITCHDESKPATH/Xclients.${XSESSION_EXEC}" ]; then
        #       exec -l "$SHELL" -c  
"$SWITCHDESKPATH/Xclients.${XSESSION_EXEC}";
        #fi

        exec $CK_XINIT_SESSION $SSH_AGENT /bin/sh -c "exec -l $SHELL  
-c \"$STARTUP\""
"""

It has been derived from the X11 session startup on SL6. Maybe we need  
to tweak this CK_XINIT_SESSION variable and change over to using  
ck-launch-session here.

Maybe this is hint enough for you to play with this some more.?...

Ok. Any results?

squeeze has CK and GNOMEv2, wheezy has CK and XFCE or GNOMEv3...
jessie has systemd and MATE, GNOMEv3, etc.

So I guess, you should stick with wheezy for CK testing and use jessie  
for systemd testing.
