Before running the upgrade I noticed that there were issues with themes so I reset to what I thought was the default theme in 16.04 and upgraded. Now I’m on 16.10 (yay!) none of the themes I have, including the default, work properly. Window borders odd colours, text that cannot be changed, menus that don’t display properly (the function is ok if I guess where things are), pop up menus are unreadable and so on.
My guess is that I need to load up GT3 themes, so my question and issue is how can I manually get rid of my old themes, get back to basics and load up (install) some compatible ones please? I know about gnome-look etc but how can i be sure that they are compatible?
This may seem a simple task, but I’m just someone who uses UM, I don’t often get into the configuration. I can do it and am happy to, just I forget how… google and searching this forum has not shed light so far.
Thanks in advance.
