I have X installed, I assume, since the ps aux shows that the X11/X is set at /var/lib/kdm, etc. (see below or infra). I will check out the "what's new with JDK 1.4 again, but don't remember that. If I do have X installed, then what is the command to make it work? It may simply be a permissions problem at this point.
