The menu item "Tools / Open Terminal" does nothing. Reproducible: Always
I've had a look at the code at [1]. texstudio attempts to launch a terminal in two different ways: 1) It queries the "org.gnome.desktop.default-applications.terminal" record through gsettings to find a terminal to use. 2) If gsettings is missing (or fails to look up the record), it falls back to "konsole" and then "xterm". Since gsettings is part of GLib, it will be available on almost all systems, so we can generally assume that it will not be missing. If the system in question has gnome-base/gsettings-desktop-schemas installed, and has not overridden the default value, gsettings will *always* return 'gnome-terminal' successfully. texstudio does not make an attempt at testing whether the application returned by gsettings actually exists on the system. If it is missing, the execution will simply fail. As such, a solution would be to set default-applications.terminal to the desired terminal app with `gsettings set <key> exec <app>'. A couple of things to note: 1) The default-applications gschema hat itself deprecated the terminal record [2], saying that "The default terminal is handled in GIO". This means that GLib's AppInfo machinery is (or at least *should* be) in charge of launching an appropriate terminal. AppInfo itself uses a hardcoded list of terminal emulators [3] for this. See [4] for a bug report and discussion on GLib's side. 2) As the terminal record is deprecated, GLib has no plan of relying on it in the future. See also [5]. 3) This does indeed mean (not only for texstudio) that the current situation for most desktop environments is that there is no way for a user to set their own desired terminal application short of sending a patch upstream to GLib and having it added to the hardcoded list, or patching GLib locally. Given all of the above, texstudio's attempt to launch a terminal will fail on almost all systems that do not have gnome-terminal installed. Again, even if the fallback emulators exist on the system, they will not be used as the successful call to gsettings will override that fallback. I personally don't think setting default-applications.terminal to the desired terminal application is a good solution. Frankly, right now, the best way to handle this would be to have upstream use GIO instead of trying to determine applications itself. That way it will work (moderately) better right now, and will support user-defined default terminals in the future once GLib decides on a way forward.
