Today after reboot I got my appearance changed, everything: Icons, Fonts and etc. except cursors. Tweak tools I tried like Ubuntu Tweak, Gnome Tweak Tool, Unity Tweak Tool don't work, I couldn't change and apply the visual theme by using them.
I found this post and partially solved the issue. Ubuntu 14.04.01 - Unity Tweak Tool doesn't change theme and font settings
Now I have weird window header and some fonts and elements. It is still got from another theme. In header it concerns control (min/max/close) buttons, gradient and shadow of top panel and Wi-Fi, sound, language switcher icons. Also after reboot all the changes I make disappear(.
Does anybody know how to make GUI completely apply the theme and make it persistent?
This is the theme I would like to work. (Unfortunately download link is broken). http://www.omgubuntu.co.uk/2014/04/lubuntu-box-theme-0-45-unity-support
