Ubuntu16.04 no dash, no launch, no menu bar after login, only desktop background solution, ubuntu16.04dash

Today, I opened my computer and entered my username and password as usual. After logging on, I found that the desktop was empty, and the launch and menu bar on the startup bar disappeared. The files on the desktop could be opened but the locations could not be dragged, unable to close (because menu bar is gone, you cannot click to close ),

After several hours of searching, find the solution as follows, and record it to help people with the same problem:

Cause: the unity Plugin is accidentally deleted or disabled.

Solution:

1. Use ctrl + alt + t to open the command line.

2. If ctrl + alt + t does not work, right-click the desktop and choose Terminal

3. If the above method still does not work, use ctrl + alt + f1 and then enter the user name and password to log on again

4. Install compizconfig-settings-manager:sudo apt-get install compizconfig-settings-manager

5. Run compizconfig-settings-manager:DISPLAY=:0 ccsm &　

6. If you use ctrl + alt + f1, you can use ctrl + alt + f7 or ctrl + alt + f8 to switch back to the graphic interface.

7. In the graphic interface, the compizconfig-settings-manager management interface is displayed. Enable Ubuntu Unity Plugin and OpenGL.

If no Ubuntu Unity Plugin is found, run sudo apt-get-f install & sudo apt-get -- reinstall install unity to download and restart compizconfig-settings-manager, you can find

Unity plugin. enable unity plugin in compizconfig-settings-manager. When this feature is enabled, a prompt is displayed, indicating a conflict with other plug-ins.

8. Select reboot in shell. After restarting, you will find that everything is back!

 

The above method is verified by myself. If you encounter any problems when using this method, you are welcome to comment on it and I will reply in time.
