For the archives. --disable-server removes xfce4-terminal ability to talk to DBUS, which is intended be used, presumably (too lazy to read sources) to force the existing xfce4-terminal to spawn a new window. Without this switch defining new environment variable applies only to "sending DBUS message" part of xfce4-terminal. And of course such custom environment variables do not propagate via DBUS. To do the same trick "terminal emulator - independent way" one needs to force a terminal to launch a shell with the needed environment variable defined via env, such as this: xfce4-terminal --command env MYVAR="wow - some text!" /bin/bash But that's fugly and probably needs copious amounts of escaping to work as intended. Disabling DBUS is cleaner, but do not try it with gnome-terminal, folks. Reco
