I was messing around with Compiz Settings Manager and result of that is that I cant see my panel bar, cant use alt+tab or start button. Is there a way to restore default Ubuntu environment? I will be grateful for your help

  • Difference is that i have cairo dock and its running fine. Its only way i can run programs like firefox. But i cant move, minimalize, resize program windows. – Ludwig Supraphonic Jun 21 '16 at 08:01
  • Yes, unable control windows is a common symptom of failed compiz plugins. You need to reenable them via compizconfig settings manager as shown in the duplicate – Sergiy Kolodyazhnyy Jun 21 '16 at 08:30

In terminal, type in sudo apt-get install --reinstall ubuntu-desktop to completely reinstall back to defaults.

To remove all compiz settings type rm -rf ~/.compiz-1 ~/.config/compiz-1 in terminal, then logout and back in.

  • still nothing...i think that`s something with compiz. Maybe i shoul remove compiz completly and the reinstall ubuntu-desktop. What do you think? – Ludwig Supraphonic Jun 21 '16 at 07:59
  • @LudwigSupraphonic I added a second command in my answer to specifically delete all compiz settings. New default settings will be created when you log back in. – Delorean Jun 21 '16 at 14:06

Or you can install "Unity Tweak Tool" and set the default settings. Open a terminal and type:

sudo apt update
sudo apt install unity-tweak-tool

  • Had wired terminal and windows behavior. removing ~/.config/compiz-1 wasn't the solution. But hitting the restore default button in the unity-tweak-tool brought my Unity back to normal behavior. THX – Tik0 Jun 13 '18 at 07:12
  • @Tik0 I am trying it now, In unity-tweak-tool, there is one 'restore default' button in each and every menu.. which button do you mean? – Chan Kim Nov 02 '18 at 04:58

Try the following, open terminal and type:

unity-reset

Alternatively:

setsid unity

But, If you can't get to the terminal cause your start buttons doesn't work you can always (this only works if you have a folder on the desktop) open the folder then go to 'computer>usr>share>applications' look for terminal inside the folder and click to open, then enter either of the above commands in the terminal.
