Got my 3D back on my Gateway

If you're in Ubuntu, and upgrade from Intrepid to Lucid, you might find this problem that I had: No 3D Effects with Intel 945 graphics. Apparently, that's because Lucid thoughtfully installs nvidia drivers, which, until removed, usurp 3D capabilities of other processors, such as Intel's. I removed a few things labelled nvidia and got 3d working again. Yay!
