Normally, a vncviewer open or close, should not impact the vncserver. On a real linux host, when we setup a vncserver, and laungh a vncviewer to it from other host, it could not impact the server, even if the viewer leave. So i think x11vnc should have the same behavior, which is: when vncviewer leave, the server still alive. ==========log on qemu when exit the vnc viewer============= 26/03/2013 08:56:21 cursor_noshape_updates_clients: 0 26/03/2013 08:56:24 cursor_noshape_updates_clients: 0 26/03/2013 08:56:29 client_count: 0 26/03/2013 08:56:29 Restored X server key autorepeat to: 1 26/03/2013 08:56:29 viewer exited. 26/03/2013 08:56:29 deleted 20 tile_row polling images. sh-4.2# sh-4.2# 35827 1 sgw 2013-08-21 20:47:10 +0000 Finally spent some time with this issue today and placed it under the debugger and also looked at the documentation of x11vnc. It states the following: -once Exit after the first successfully connected viewer disconnects, opposite of -forever. This is the Default. Notice this is default, the correct parameter would be -forever to get the behavior your talking about. So I think the default of x11vnc should be kept. -shared VNC display is shared, i.e. more than one viewer can connect at the same time (default off). -once Exit after the first successfully connected viewer disconnects, opposite of -forever. This is the Default. -forever Keep listening for more connections rather than exiting as soon as the first client(s) disconnect. Same as -many To get the standard non-shared VNC behavior where when a new VNC client connects the existing VNC client is dropped use: -nevershared -forever This method can also be used to guard against hung TCP connections that do not go away.
