Thought it would be better to post a new topic instead of resurrecting an old one: https://forum.obarun.org/viewtopic.php?id=1348&p=2

I've followed the advice from @ eric at post # 23, but permission errors still pop up from Thunar about not having authorization when click-to-mount is desired. My system is up-to-date as of now.

As per the advice, I've switched my ~/.xsession to:

# !/usr/bin/bash

_user=hyperspace

list=( $(ls -A1 /home/${_user}/.66/conf/svscan@ ${_user}) )
for i in ${list[@ ]};do
    var=( $(</home/${_user}/.66/conf/svscan@ ${_user}/${i}) )
    for j in ${var[@ ]}; do
		export ${j}
    done
done

66-all up

But the permission errors still persist in Thunar.

For now, I've reverted to the "wrong" way where /usr/share/sddm/scripts/Xsession is modified instead, as suggested by @ negative at post # 12:

if [ -z "$*" ]; then
    exec xmessage -center -buttons OK:0 -default OK "Sorry, $DESKTOP_SESSION is>
else
    if [ -x /usr/bin/ck-launch-session ]; then
        exec ck-launch-session dbus-run-session $@
    else
        exec $@
    fi
fi

Where "dbus-run-session" is the change suggested. This works without permission errors for click-to-mount.

This isn't really an urgent matter for me so no need to be too alarmed, but just letting you guys know just in case.
