I have 18.04 installed on 3 laptops (one is a server) and a desktop. Only in the upstairs laptop server does MATE Tweak offer me the opportunity to select another layout.
For instance on this laptop, I have working MATE Tweaks in both 16.04 and 17.10 but not in 18.04. All of these are fresh installs, not upgrades of any sort. I'm not a believer in upgrades from one version to the next.
This is 16.04--------------
This is 17.10--------------
and 18.04 displays above.
My directory (and the other non-working installs) has what it needs - see below. I've tried several ideas found on this forum but nothing seems to get me more than a Gnome2 offering. Not actually interested in getting this working so much but I am interested in finding out what is holding this thing back.
Got any good ideas?
