Ubuntu – Appearance does not change on switching the theme


If I select Radiance or Ambiance in the menu show in the following picture, my whole theme does not change. It only changes the title bar.

How can I resolve this problem? Or how can I reset the theme to default?

Install dconf-editor if you don't have it, and then go to


and check "active." One thing I've also noticed when this happens is that the media keys stop working: enable org.gnome.settings-daemon.plugins.media keys. There also might be some more plugins you should enable.

Problem cause: when unity-greeter is run (by the lightdm --test-mode command in my case), it disables a lot of settings-daemon plugins that have to be manually reenabled.

I got all of my info from this thread: http://ubuntuforums.org/showthread.php?t=1861476
