The settings for my linux mint OS have somehow changed automatically. The wallpaper has changed to default background, the mouse and touchpad settings are different, and I can't see the 'Computer' icon on my desktop either. I've tried restarting a couple times and in some restarts I've seen this message:

What seems to be the problem here?

rootuser by any chance? By"... somehow changed automatically ..."you mean you haven't touched configuration at all? Nothing happens automagically unless you e.g. did a system upgrade or changed something. – htor Jan 15 '12 at 17:18
