I did as you suggested. When I boot up, I get "Cannot enter home directory. Using /." Clicked "Okay," then got "Kstartupconfig4 does not exist or fails. The error code is 3. check." Clicked "OK," then got "The session was locked by bill."
This is a fresh install with all recent updates. Since I am the only one who uses this machine, I am not too concerned about this issue, but thanks for all of your help.
I have been using the forums to solve all of my newbie problems for more than two years now, and this is my first post, so that tells you how great this site is.
I don't know what impact this may have had, but I used "apt-get update," and "apt-get upgrade," before reading Texstar's October post telling us not to do so. Ooops!
