I was playing around with Compiz and unity-tweak-tool and suddenly unity stopped working, tried restarting but it wasn't effective, reinstalled unity and it started to work normally.

After that, I just noticed that unity-tweak-tool is missing. I tried to install it from Software Center and after that tried to change theme but it wasn't working, once again tried to reinstall unity & tweak-tool but it was not effective.

OS: Ubuntu 16.04 LTS


I noticed you mention two consecutive installations without any un-installation. Suggests me that installation is failing. Could you type on your terminal

sudo apt-get install unity-tweak-tool

and post us if you observe any errors? It should normally say "already the newest version" and quit.

  • Yeah right it's saying that the latest version is already installed. – Varand Vartanian May 26 '16 at 4:26
  • So what does "not working" refer to? When you follow @pomba, no GUI appears? – Copper May 26 '16 at 23:23

Bring up your terminal by hitting Ctrl+Alt+T

Just type unity-tweak-tool in your terminal and it will bring up unity-tweak-tool UI.
