Try the following methods:

In ubuntu 11.10, When you modify compizconfig-settings-, some necessary plug-ins are disabled, and the Unity interface disappears without lancher, I read a lot of information online. The solution is as follows:

Reset unity, open terminal (CTR + ALT + F1 or Alt + F2, enter gnome-terminal), and enter:

sudo apt-get install compizconfig-settings-manager

sudo unity --reset

Generally, it takes one minute to reset unity. During the running process, the console may have no feedback input. For the sake of insurance, terminate the program two to three minutes later by CTR + C.

Then restart the running of the following command:

sudo service gdm restart

Or

sudo service lightdm restart

If the above method is not successful, you can re-press compiz and unity, the command is as follows:

sudo apt-get update
sudo apt-get install compiz
sudo apt-get install compizconfig-settings-manager
sudo apt-get install unity

Then, restart the system to run the following command.

If the title bar of your window disappears, run the following command:

gtk-window-decorator --replace

Set the compiz effect and click the conflict option at will to solve the problem that causes the toolbar to disappear on the side.
Press CTRL + ALT + F1 to log on. Enter unity -- reset and press CTRL + ALT + F9 to exit.
Remember not to click on the visual effect if you are not sure. If you want to click it, you can go to the Ubuntu Chinese forum to check the practices of the experts and learn how to use it.

 

 

Finally, I found the solution. I switched to the terminal by pressing CTRL + ALT + T, input killall gnome-session, and then input ccsm to enable the unity plug-in.

6 solutions to 3D desktop crashes or crashes
Case 1: The desktop screen does not seem to respond when you operate the mouse or keyboard.


Press Ctrl Alt F1 to switch to the character terminal. You do not need to log on. press Alt F7 to switch back to the graphic interface.


This step is equivalent to reload the window by using the fusion-icon in earlier versions of ubuntu, just refresh the desktop (the desktop is the "root window ").
Case 2: The window has no title bar and no border. The starter bar and top menu bar on the left side of Unity disappear, and the mouse and keyboard operations are normal.
Press Ctrl Alt F1 to switch to the character terminal, and enter the user name and password to log on,
(Note during logon: do not be fooled by the lights on the keyboard. If it is on, double-click it. This is the real digital input state .)
Run the following command to end the gnome process and return to the user logon page:

Code:

Killall gnome-session

 

 

Case 3: After logging on again, the desktop is blank, with only wallpaper left, and nothing else.
Press Ctrl Alt F1 to switch to the character terminal, and enter the user name and password to log on,

Code:

Rm-RF. config/compiz *. gconf/apps/compiz *

Code: killall gnome-session
