Stop Ubuntu greying out stalled program windows as quickly

If you have desktop effects enabled, Ubuntu will "grey out" program windows that it thinks have either crashed or stalled. This can be a useful visual indication that something has gone wrong but the delay before it happens—five seconds—is just too quick. Programs like Synap-tic have a habit of pondering their next action for slightly longer than that, and that can cause them to "grey out".

You can alter the time-out by editing a setting using gconf-editor. Navigate to /apps/compiz/general/allscreens/options and change the ping_delay key to 10000. This will change the "greying out" delay to 10 seconds (10,000ms). For 15 seconds, change the setting to 15000.
