Created attachment 8615 Fix inhibitor lock Inhibit (and unhibit) locks are related to org.gnome.ScreenSaver interface, but on Xfce session this service is not available, so these locks always fail. This patch fixes this issue (as we support systemd and ConsoleKit2, we use these services).
Thanks for the patch! Applied with the following commit. https://git.xfce.org/apps/xfce4-screensaver/commit/?id=e284490ab23a86794254edcc005865353e206178
