cannot install compiz for my kubuntu

you need to have extra repositories enabled..

To enable universe software repositories do..

Start Adept by choosing K Menu->System->Adept (Package Manager) from the Desktop menu system.

Select View->Manage Repositories in the Adept package manager window.

To enable the Universe repository, find the repository line with the Universe Component, and right click the line and select Enable.

after getting all the required repositories enabled

Type the following command in a Konsole (KMenu -> System -> Konsole)

sudo apt-get update

Then type,

sudo apt-get install compizconfig-settings-manager

To configure compiz do,
KMenu -> Settings -> CompizConfig Settings Manager or KMenu -> Settings -> Advanced Desktop Effects Settings

To add a startup:

Open Konsole (KMenu -> System -> Konsole) and type in these commands:

echo "compiz --replace" > ~/.kde/Autostart/startcompiz.sh
chmod +x ~/.kde/Autostart/startcompiz.sh

and below are the most used short cuts:
SUPER+SHIFT+DRAG LEFT MOUSE = draw fire
SUPER+SHIFT+C = clear fire
CTRL+ALT+DRAG LEFT MOUSE = rotate cube
CTRL+ALT+LEFT ARROW = rotate cube
CTRL+ALT+DOWN ARROW = flat desktop
SHIFT+ALT+UP=initiate window picker
CTRL+ALT+DOWN=unfold cube
ALT+TAB=window switch
SUPER+TAB=flip switcher or ring switcher depending on which is enabled.
ALT+F7=initiate 'move windows'
SHIFT+F9=water effect
SHIFT+F10=slow animations
CTRL+ALT+D=show desktop

For Grouping and Tabbing:
SUPER+S=Select Single Window
SUPER+T=Tab Group
SUPER+Left=Change Left Tab
SUPER+Right=Change Right Tab
SUPER+G=Group Windows
SUPER+U=Ungroup Windows
SUPER+R=Remove Group Window
SUPER+C=Close Group
SUPER+X=Ignore Group
hold the super button then select the windows you want to group and then hit super+g

also You can add new shortcuts.. all that you have to do is just you can select one of the plugin(double click on it) and in actions tab of the plugin, under bindings you can change the shortcuts. You can even add a screen edge as a binding so that when you move your mouse cursor to screen edge(say top left) compiz will execute the particular action. It goes really nice with expo plugin. have a great time with compiz fusion!
(the one with windows logo on it (in some keyboards along with windows logo "start" is printed)
This is the super key..

Note: This is just for your Information..

To have desktop effects enabled in kubuntu in the same way as ubuntu do:

Go to KDE Start Menu->"Add/Remove Programs", then once Adept Installer loads, you can search for "desktop effects". A package called desktop-effects will be found. Its description says that it's a "preferences applet for configuring desktop effects". Install it.

Once it's installed, go to KDE Start Menu->System->Konsole. Type in the command:

desktop-effects

then press enter. It will bring up a wizard which allows you to choose which effects you'd like to enable.

Hope the info helps
