Good thoughts, both. But, no such luck. I also checked the /etc
equivalents, and others mentioned in man bash, and found none such.
However, in the course of doing that I noticed that .Xauthority is now
a regular file, owned by root:root and 0600, as it should be. The date
on it is earlier this morning, when I logged in via SSH from another
machine. With the su alias I described earlier, xclock works.
