This is a great forum!
Never could I have imagined to receive so many replies in such a short time, even for such a relatively esoteric question.
Again, as I mentioned in the beginning, I am “experimenting” switching to Fedora, after having used Ubuntu, almost exclusively, since 9.04.
The reason I want to consider something other than Ubuntu was that I need a Chinese language environment, but the Ubuntu Chinese language team seems to have been withholding updates for some key components (e.g., ibus, ibus-libpinyin, ibus-pinyin, etc), apparently in favor of some commercial alternatives.
With only about one week of experimentation, I am actually seeing myself using Fedora 26 as my main OS.
MATE made this switch, not only possible, but also almost painless!
And I am very appreciative of the fact that, although this is a “Ubuntu” MATE forum, it does not discriminate against Fedora-wanna-bes.
