We use the following modification to gdmflexiserver to lock the
screen before switching users on openSUSE:
https://build.opensuse.org/package/view_file?file=lightdm-lock-screen-before-switch.patch&package=lightdm&project=X11%3Axfce&srcmd5=4fd8b507ca5e29e2fa9c5edb483f12b8
Apart from xscreensaver and gnome-screenserver it also works
with the KDE screensaver slock and xlock/xlockmore.
