This is (rarely used) special mode where, at server regeneration (when last client exited), Xnest is additionally terminating and restarting it's upstream connection, thus also recreating it's main window, etc. That mode is only meant for special debug scenarios, not suited for practical use. And the same can be achieved by just terminating the whole Xnest process (-terminate cmdline arg) and restrting it. Signed-off-by: Enrico Weigelt, metux IT consult <info@metux.net>
