So what is the solution? This happened to me too after I did an update about a month or so ago. I was running Hoary, but added Breezy to my "universe"? without realizing it would affect the updates? I'm kind of thinking I don't have nvidia, and all I did was run the update. What do you guys reccomend? I'm ready to reinstall the whole system, but maybe there's an easier fix? Thanks, Greg
