I have tried it on several distros before and it always causes problems because you get a million more packages intermingled with your already installed packages and sometimes you get conflicts or whatever. But it usually messes up my system. is there a safe way to have several desktops installed? or do you pretty much install a new one then remove the old one? thanks
There really isn’t any such thing as a “pure mate experience” for instance normal install likely contains VLC/Smplayer for multimedia, libre office for office docs, and firefox or chromium for web browsing. Not only are none of these mate apps most users probably spend most of their time using apps like these than their file manager.
Then if you look at the other mate apps. Mate Terminal is hardly the best terminal nor is Atril the best pdf viewer. Kitty is a better terminal and zathura and Okular are both better PDF readers. Pluma is a mediocre text editor.
The useful parts of an env are its settings menu, window manager, bar, and file manager. Pick one you like and then pick useful apps to go with it.
