A useful trick is to set the XAUTHORITY environment variable. For example,
$ XAUTHORITY=$HOME/.Xauthority
$ export XAUTHORITY
or in csh
% setenv XAUTHORITY $HOME/.Xauthority
Now when you use su, the XAUTHORITY variable still points to the correct
file and you can access the display. Note that `su -l' does not work,
since the XAUTHORITY environment variable is unset.
