AS hci user with the tcsh you should be able to execute an alais that will set your DISPLAY variable
it is called
setdisplay
and would look like this in your /home/hci/.cshrc.local.end
alias setdisplay setenv DISPLAY `who am i | awk “‘”‘{ print $6}'”‘” | sed “‘”s/”[()]”//g”‘”`:0.0
or you could execute the entire cmd yourself
setenv DISPLAY `who am i | awk ‘{ print $6}’ | sed ‘s/[()]//g’`:0.0
