Thanks, I am an almost total Linux novice. I am running an ATI video card and gather from your notes below that the crash is somehow related to video. I have no idea what the compiz programs are or how to reinstall them. I do find Ubuntu 8.04 more useful than 7.10, which was the first Ubuntu that would actually install to my computer. I think that in a few more iterations Ubuntu will displace Windows on my machines. But not yet. So, what is compiz and how do I get the files to reinstall them?
