In Ubuntu 16.04, I have a lovely Solarized theme. Previously it made my title bars a nice dark blue and replaced the orange and grey Unity-themed icons with something more subtle. But today, upon logging in, I found the old Unity grey and orange title bars again.
The Unity glare boxes have also returned to the launcher as you can see in my screenshots.
I have already taken the advice of this answer but nothing changed. Any ideas on how to return my theme to its prior glory?
