As discussed here, gtk-launch can launch applications either directly or in a terminal window, depending on whether the .desktop file specifies that the application runs in a terminal. It seems to me that this terminal is not the x-terminal-emulator from the alternative system (it doesn't change when i update the alternatives).Is there a way to specify which terminal emulator gtk-launch should use?
how to specify which terminal is used by gtk-launch
terminal emulator;.desktop
