I keep hearing how Ubuntu has finally nailed the dual head hassles of the past, and now you can just plug in an external monitor and go. Alas I've never had that experience, either with this Dell Vostro 1400 or either of the two IBM Thinkpads I've run Ubuntu on.The IBMs were both 1024×768 resolution, as is my external monitor. The Dell is a less standard 1280×800 resolution. I also, on occasion plug it into my LCD TV, but that's another story.
