I switched from Windows to Ubuntu a while ago now, but various popup dialogue boxes that prompt for confirmations continue to irritate me. Especially the ones when closing a Terminal that's running another process ("Close This Terminal?: There is still a process running in this terminal. Closing the terminal will kill it." Cancel | Close Terminal), the one about updates that runs intermittently on start up ("Your Ubuntu release is not supported anymore"), and the one when I connect my phone ("You have inserted a digital media player").
Is there a way to simply disable all pop-up dialogue boxes?
I'm using 11.10 due to a compatibility issue I had with 12 and a general dislike of 13.
