Changes to Main Menu are not saved

Question

I am unable to find a way to edit the Main Menu on my system (see attached image of my menu). I have tried using "alacarte", "mozo" and "menulibre". When I make changes to the menu in (for example) mozo, the change shows up in the mozo app but then when I go to the menu itself, the change does not show up even if I logout and login or if I reboot. In other words, my changes are not properly saved to my system, using any of these three apps. My system information: $ wmctrl -m Name: Metacity (Marco)

$ printf 'Desktop: %s\nSession: %s\n' "$XDG_CURRENT_DESKTOP" "$GDMSESSION" Desktop: MATE Session: mate

$ lsb_release -a Distributor ID: Ubuntu Description: Ubuntu 20.04.5 LTS Release: 20.04 Codename: focal

Does anyone know what's going on and how to fix it?

Answer 1

Okay, I solved this problem as follows: Using the "Mate Tweak" application (from the universe repository), in the "Panel" tab I changed the "Panel" from "Familiar" to "Traditional". Then I removed the "alacarte" and "menulibre" menu editors ...leaving only "mozo" which is apparently the correct Menu editor to use for Mate. I noticed that when deleting an application, it stays on the menu until I log out and log back in - but other changes show up instantly in the menu without logging-out. The "Traditional" menu looks slightly different; it has three Top-level options: "Applications, Places, System" but I'm totally okay with that - in fact I prefer it.
