If Thomas is using "setenv", he might be in csh/tcsh, in which case
he'd need to use
env DISPLAY=:0 <your-application>
to get the desired effect. However, I'm deeply curious about the
results he's reporting. Are "Konsole" and "Mate" both terminals
that are running in the same session? How do we explain the
different values of $DISPLAY if they are?
Of course, if those results are from different sessions, or even
different computers, then that explains it.
