Thank you very much for this report. Since you are testing the Xubuntu lucid-desktop-amd64.iso daily-live image, can you try with the latest image. There have been many changes since the image reported here. It would help us greatly if you could test with it so we can work on getting it fixed in the next release of Xubuntu. You can find out more about the development release at http://www.ubuntu.com/testing/ . The Xubuntu daily-live images are available at http://cdimages.ubuntu.com/xubuntu/daily-live/current/ . Thanks again and we appreciate your help.
