How to install compiz
Answer to the question
Follow the below steps to install compiz in Ubuntu Linux 12.04.
1.To open a terminal without mouse access, press Ctrl + Alt + T. If you get stuck in your desktop environment and nothing responds, you can open a full screen shell by hitting Ctrl + Alt + F1. You can leave the shell again by pressing Ctrl + Alt + F7 (if it's not F7, try out F8 or some other keys).
should reset the Unity desktop environment as well as the settings you did in the CompizConfig Settings Manager that you will use to configure Compiz. With
you can soft-restart your computer. Don't let yourself discourage by error reports and stuff, you probably won't get around these. If you get error messages and Unity crashes, try to reboot and repeat your last steps - funny enough, I got error reports all the way through configuring CCSM and after some attempts everything just worked.
2 Install Compiz
To install Compiz, open a terminal (Dash > Installed Applications > Terminal) and enter following:
sudo apt-get install compiz compizconfig-settings-manager compiz-fusion-plugins-extra compiz-fusion-plugins-main compiz-plugins
3 Configuring CompizConfig Settings Manager
Open CompizConfig Settings Manager by searching Dash for ccsm. Take the warning that comes up serious! In the CCSM window, scroll down to the Ubuntu Unity Plugin and click it:
In the plugin's menu, make sure the Enable Ubuntu Unity Plugin checkbox is checked (if it's not you would have most likely noticed it anyway. The launcher and everything would be gone then - if you had that problem from the start, open a terminal in the way described above and start ccsm by entering
Click Back to go back to the main menu. Check the Desktop Cube checkbox. A message will pop up instantly, asking if you want to disable Desktop Wall in favor of the cube - click Disable Desktop Wall (by now you could already have come across some errors - just reset or reboot if it's needed and try again):
CCSM will most likely ask you more questions if you enable the cube for the first time. Enable all the things needed for it (OpenGL, Compositing). Next check the Rotate Cube plugin. Also click it to configure additional rotation settings (zooming out while rotating as well as slowing speed and acceleration down gives nices effects). Afterwards scroll up again and enter the General Options:
On the Desktop Size tab, you can configure how many sides you want your desktop cube to have. A decent cube should have at least 4 sides, so set the Horizontal Virtual Size to 4 or higher:
To test if the cube works, hit Ctrl + Alt + arrow keys Left/Right. The desktop changing animation should be the one you configured with CCSM now - if it isn't, log out and in to try again.
