Thank you for the tips! Extending your idea, I found another
solution:

$ export XAUTHORITY=$HOME/.Xauthority
$ su

That's it. I put the first line into my (ordinary user's)
~/.bashrc or ~/.bash_profile . When I say "su -" my
environmental variables are discarded, but when I say "su" my
environmental variables are inherited by root.

This method is better for me than to put
"export XAUTHORITY=/home/<my_username>/.Xauthority" into root's
.bashrc, because my system administrators sometimes log in
to my machine and become root. When they do so, they might
send their windows to my screen without their knowing!

A slight downside is that my own, nonstandard environment
variables are inherited by root, too. (HOME seems to be
overriden by the su command, so that you don't have to worry too
much.)

Unless I am missing something, I think you are creating a security
hole doing it this way.
