Dbus issue when trying to run Wayland session

My distro is based on Slackware, therefore it doesn't have systemd, but SysVinit + elogind. I'm trying to use LightDM to initiliaze my desktop environment sessions, but I have either dbus services working properly or Wayland working. My /etc/lightdm/Xsession file is like this:

[ -z "$BASH" ] && exec $SHELL --login $0 "$@"
shopt -q login_shell || exec $SHELL --login $0 "$@"
set +o posix

userresources=$HOME/.Xresources
usermodmap=$HOME/.Xmodmap
sysresources=/etc/X11/xinit/.Xresources
sysmodmap=/etc/X11/xinit/.Xmodmap

[ -f $sysresources ] && xrdb -merge $sysresources
[ -f $sysmodmap ] && xmodmap $sysmodmap
[ -f $userresources ] && xrdb -merge $userresources
[ -f $usermodmap ] && xmodmap $usermodmap

dbus-launch --exit-with-session $@

It works fine, except if I want to start a Wayland session, which in this case it doesn't load in LXQt 2.1.0 or Cinnamon 6.4.9. The log ~/.xsession-errors says something like:

dbus-update-activation-environment: error: unable to connect to D-Bus: Failed to connect to socket /tmp/dbus-6WcQhFZXE2: No such file or directory

If I change the last line of /etc/lightdm/Xsession to dbus-run-session -- $@, then the Wayland sessions work, however some services stop working properly due to a dbus problem. For instance, cron daemon (crond), which is executed in a boot script that runs before Xsession: if cron is set to shutdown my Xfce session, it doesn't find the Xfce dbus session: Also, when using Wayland the error above always happens. Is there a clean solution that fixes the issues I'm facing?
