Some users reported that the Ubuntu’s graphical user interface has disappeared after upgrading to Ubuntu 16.04. I personally prefer a clean install to avoid such issues, but if you have already hit the upgrade button and stuck with the user interface including all menus, then you are not alone.
The problem comes up because Ubuntu’s Unity which is nothing but graphical user interface app fails to start. You are left with only a desktop with wallpaper background and that’s it – no icons, menus etc.. Here is a step-by-step fix to this annoying problem.
STEP 1: INSTALL COMPIZ SETTINGS MANAGER
Launch ‘Terminal’. Now that you don’t have a graphical user interface, you try launching terminal in one of following ways:
- Press Control+Alt+T or
- Right-click on the desktop and Select “Open Terminal” from the right-click context menu.
- If nothing is working, you may have to change to a “hard” terminal by pressing Ctrl+Alt+F1 and log in.
In the terminal, type or copy-paste this following command.
sudo apt-get install compizconfig-settings-manager
You may have to enter the root password to complete the installation.
STEP 2: RUN COMPIZ
Enter the following command in the Terminal.
DISPLAY=:0 ccsm &
You will see CompizConfig Settings Manager dialog box. Click ‘OK’ for the warning message.
STEP 3: ENABLE UBUNTU UNITY PLUGIN
Finally, it’s time to enable the Ubuntu Unity Plugin. Scroll down in the settings window to ‘Desktop’ section and click on “Ubuntu Unity Plugin”.
Click “Enable Ubuntu Unity Plugin” and close the window. Click “OK” for the warning, if any pops-up.
You should now see all the menus, icons, and all stuff back! If not, restart Ubuntu and you should be fine.
That’s it. Did the solution work for you? Do let us know your feedback in comments below.
