I have the same problem. I really don’t understad why Antergos made that decission with Mate. If I would like to have mint, I would install mint. What I want from Mate is the good and old gnome2.
Is it there any way to remove completely the Antergos’ mate and install the classic one?
I tried installing Mate-Tweak, but from there I can’t change the theme to Gnome (it doens’t make anything).
It would be nice to have some solution for it.
