I've just posted this:
on the main site, but I'm not really sure whether this is the right place for it, or rather Super User; the thing is, while I'm running Linux, it's not entirely a Linux-y issue, and you get the same problem on other operating systems as well. And, actually, I'm running Ubuntu, so in the other direction you could say it's Ubuntu-specific enough to ask there.
How do I call this?
