It would help me to know what the ping delay is - if I'm going to make a change to something I'd prefer to have some idea of what I am doing and why.

If you have the compiz settings manager installed, go in General Options and adjust the Ping delay. Currently it's set to 5000 milliseconds. It doesn't look like it can be disabled, so setting the value to an extremely high number should prevent it from activating under normal usage. Alternatively, if you don't have ccsm installed, you can adjust the ping delay value from gconf-editor. Go to /apps/compiz/general/allscreens/ options/ping_delay. -- sktsee </blockquote></div>
