I tried to add <property name="LockCommand" type="string" value=""/> to both /etc/xdg/xfce4/xfconf/xfce-perchannel-xml/xfce4-session.xml ~/.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-session.xml without success (I still get "/general/LockCommand does not exist") Is it expected ? i.e. does the fix affect the build -- hence I have to wait for updated package builds for my distro (Fedora 22 beta) --, or am I just modifying the wrong files ?
running from the command line: xfconf-query -c xfce4-session -p /general/LockCommand -s "" should also prevent the popup while still allowing the defaults.
